Some television shows are entertaining, but others create an entire world that viewers cannot stop thinking about long after the final episode ends. Stranger Things belongs firmly in the second category. With its mysterious alternate dimension, secret government experiments, extraordinary children, nostalgic 1980s atmosphere, and friendships tested by terrifying circumstances, the Netflix hit has become a defining series for fans of science fiction and supernatural storytelling. Its greatest strength lies in the way it combines high-stakes mysteries with deeply human emotions, making the strange and impossible feel surprisingly relatable.
For viewers who have finished the series and are searching for their next binge-worthy obsession, the good news is that science fiction television has plenty of fascinating worlds to explore. From small towns hiding dangerous secrets to futuristic societies shaped by mysterious forces, several shows capture the same combination of suspense, supernatural intrigue, coming-of-age drama, and unexpected twists. While none recreates the exact magic of Hawkins, Indiana, these seven sci-fi series offer compelling reasons to stay up for just one more episode.
1. Dark : A Small Town Where Time Becomes the Biggest Mystery
Best for: Viewers who love complicated mysteries, secretive families, and stories that reward close attention.
If the unexplained disappearances and hidden dimensions of Stranger Things kept you hooked, Dark takes that fascination with the unknown and pushes it into much more complex territory. Set in the fictional German town of Winden, the series begins with the disappearance of a young boy, an unsettling event that exposes long-buried secrets connecting several local families. As the investigation develops, the mystery expands beyond missing children into a disturbing web of time travel, inherited trauma, and events that connect different generations.
What makes Dark particularly compelling is the way it transforms an ordinary community into the centre of an extraordinary scientific puzzle. Its forests, caves, power plants, and quiet residential streets create an atmosphere of constant unease, much like the seemingly peaceful town of Hawkins. However, where Stranger Things often balances its darker moments with humour and youthful adventure, Dark adopts a heavier, more philosophical tone. Every discovery raises new questions, and even seemingly insignificant details can become important later in the story.
The series is especially rewarding for viewers who enjoy piecing together clues rather than simply watching the action unfold. Its intricate timeline and interconnected characters demand attention, but that complexity is also part of its appeal. If you want a dark science fiction thriller that explores whether people can escape their past or change their future, Dark deserves a place at the top of your watchlist.
2. The OA : A Mysterious Disappearance That Defies Explanation
Best for: Fans of unexplained phenomena, parallel dimensions, and emotionally driven science fiction.
Few series create a sense of mystery quite like The OA. The story follows Prairie Johnson, a young woman who returns home after disappearing for seven years. Once blind, Prairie can now see, but she refuses to explain the full circumstances of her disappearance to authorities or even to the people closest to her. Instead, she gathers a small group of strangers and begins sharing an extraordinary account involving captivity, near-death experiences, and realities that may extend beyond the boundaries of ordinary human understanding.
Like Stranger Things, The OA places mysterious events at the centre of a story about people searching for answers in a world that refuses to make sense. Both shows explore the possibility that reality is more complicated than it appears, and both feature characters whose experiences isolate them from those who cannot understand what they have witnessed. However, The OA is less concerned with monsters and action sequences than with consciousness, belief, human connection, and the possibility of existence beyond a single reality.
Its distinctive storytelling style makes it an intriguing choice for viewers who prefer science fiction that leaves room for interpretation. The series moves between intimate conversations and increasingly unusual revelations, creating an atmosphere that can feel dreamlike, unsettling, and deeply emotional. It is not a straightforward mystery with simple answers, and that ambiguity is precisely what makes it memorable. Although the story remains unfinished following its cancellation, The OA offers an unusual perspective on parallel dimensions and the limits of human perception.
3. Locke & Key : Supernatural Secrets Hidden Inside an Old House
Best for: Viewers who enjoy young protagonists, supernatural discoveries, family secrets, and mysterious powers.
Imagine discovering that an old family home contains keys capable of unlocking extraordinary abilities, secret rooms, and doors to places that should not exist. That is the central premise of Locke & Key, a supernatural fantasy series that blends mystery, horror, and coming-of-age drama into an accessible, visually imaginative adventure.
After a family tragedy, the Locke siblings move into their ancestral home, Keyhouse, where they begin discovering magical keys hidden throughout the property. Each key has a different power, transforming ordinary spaces into gateways to extraordinary experiences. However, these discoveries also attract dangerous attention, forcing the siblings to uncover the history of the house while protecting themselves from threats they barely understand.
The appeal for Stranger Things fans is easy to recognise. Both series place young characters at the heart of supernatural mysteries, allowing childhood curiosity to develop into genuine courage as the danger grows. Friendship, family loyalty, grief, and growing up are just as important as the fantastical elements. The central characters must also learn that extraordinary discoveries often carry consequences, especially when powerful forces want to exploit them.
Although Locke & Key leans more heavily into magical fantasy than scientific experimentation, it captures the excitement of discovering that the familiar world contains hidden rules and frightening possibilities. Its mysterious artefacts, secret histories, and supernatural adversaries make it an entertaining option for viewers seeking a series that combines youthful adventure with darker themes. With three seasons available, it also offers a contained story for anyone looking for a supernatural mystery to binge-watch over a weekend.
4. The Umbrella Academy : Extraordinary Siblings, Strange Powers, and an Approaching Apocalypse
Best for: Fans of unusual superpowers, dysfunctional families, dark humour, and reality-threatening mysteries.
What happens when a group of children with extraordinary abilities grow up without the emotional support needed to become a functional family? The Umbrella Academy explores that question through a wildly unconventional team of adopted siblings who reunite after the death of their eccentric billionaire father. Their reunion quickly turns into a much larger crisis when they discover that the world may be heading towards an apocalypse, and their own complicated past could be connected to it.
The series shares several important ingredients with Stranger Things, including gifted young characters, secretive experiments, mysterious events, and threats that extend far beyond ordinary human experience. Yet its personality is very different. Rather than focusing on a close-knit group of friends in a small American town, The Umbrella Academy follows emotionally damaged siblings whose superhuman abilities cannot protect them from jealousy, regret, family conflict, or their own destructive decisions.
Its unusual blend of science fiction, superhero storytelling, time travel, and absurdist humour keeps the narrative unpredictable. One moment may involve a dangerous confrontation with powerful enemies, while the next explores the awkwardness of family relationships or the consequences of a decision made decades earlier. The characters are flawed, frequently frustrating, and often surprisingly relatable despite their extraordinary circumstances.
For viewers who enjoyed the supernatural stakes of Stranger Things but want something with a more eccentric sense of humour, The Umbrella Academy is a strong choice. It offers imaginative world-building, unconventional heroes, and a recurring reminder that saving the world can be considerably more difficult when the people responsible cannot agree on what to do next.
5. Fringe : Secret Experiments and Science That Pushes Reality to Its Limits
Best for: Viewers who enjoy government conspiracies, unexplained scientific events, and investigative science fiction.
One of the most intriguing aspects of Stranger Things is the suggestion that secret experiments can uncover forces far more dangerous than the scientists conducting them realise. Fringe takes a similar idea and builds an entire investigative series around it. The story follows FBI agent Olivia Dunham, eccentric scientist Walter Bishop, and his son Peter as they investigate bizarre incidents that appear to violate the known laws of science.
These cases include unusual biological phenomena, experimental technologies, and events that gradually reveal a much larger mystery. What begins as a collection of strange investigations develops into a complex narrative involving parallel universes, scientific ambition, and the consequences of crossing boundaries that may have been better left untouched.
The connection to Stranger Things is particularly clear in the show’s treatment of experimental science. Both series suggest that institutions operating behind closed doors may understand less about their discoveries than they claim. Both also explore the human consequences of scientific breakthroughs, particularly when powerful technologies interfere with ordinary lives. However, Fringe adopts a procedural format in its early episodes, giving viewers individual mysteries to solve before the larger mythology takes centre stage.
The emotional relationship between Walter and Peter adds depth to the scientific spectacle. Beneath the strange experiments and increasingly ambitious storylines is a story about family, guilt, sacrifice, and the desire to correct past mistakes. With five seasons, Fringe offers a substantial viewing experience for anyone seeking intelligent science fiction with a long-running central mystery. If the laboratory secrets and alternate-dimension elements of Stranger Things were among your favourite features, this series is particularly worth exploring.
6. The Society : Teenagers Forced to Build a World of Their Own
Best for: Viewers who enjoy teen-led mysteries, isolated communities, and the darker side of growing up.
What if an entire town’s adult population suddenly disappeared, leaving teenagers to survive without knowing what happened or whether help would ever arrive? The Society explores this unsettling premise by following a group of young people who return from a school trip to discover that everyone else in their town has vanished. With no clear explanation, no functioning connection to the outside world, and no adults to guide them, they must establish their own rules while searching for answers.
Although the series leans more towards science fiction drama than supernatural horror, its central mystery offers a familiar appeal to fans of Stranger Things. Both stories place young people in extraordinary circumstances and force them to confront dangers that adults either cannot understand or are no longer available to address. The difference is that The Society focuses less on defeating a monstrous enemy and more on the social consequences of an unexplained disappearance.
As the teenagers attempt to organise their community, questions of leadership, justice, loyalty, and survival become increasingly important. Friendships are tested, alliances shift, and the desire to maintain order begins to conflict with personal ambition. The resulting drama demonstrates how quickly a community can change when its usual institutions disappear and ordinary people are forced to take responsibility for decisions with serious consequences.
The show’s greatest strength is its ability to turn an apparently impossible situation into a study of human behaviour. Its characters must decide not only what happened to their town but also what kind of society they want to create. For viewers who enjoyed watching the young characters in Stranger Things work together against seemingly impossible odds, this series offers a darker, more socially focused alternative. One important caveat: The Society was cancelled after its first season, so its central mystery does not receive a complete resolution.
7. Paper Girls : Time Travel, Childhood Friendships, and an Unexpected Adventure
Best for: Fans of 1980s nostalgia, young protagonists, time travel, and friendships tested by extraordinary events.
For viewers who love the nostalgic atmosphere of Stranger Things, Paper Girls offers a particularly appealing combination of childhood adventure and science fiction. Based on the comic-book series by Brian K. Vaughan and Cliff Chiang, the story begins in 1988, when four teenage newspaper delivery girls encounter an extraordinary event during their early-morning paper route. Their ordinary lives quickly give way to a dangerous journey involving time travel, conflicting groups from the future, and unexpected encounters with different versions of themselves.
The series captures the thrill of being young and discovering that the world is far stranger than anyone could have imagined. Like Stranger Things, it uses the experiences of its young characters to explore friendship, identity, fear, and the difficult transition from childhood to adulthood. Its period setting also creates a strong sense of nostalgia, although its focus is more directly connected to time travel and futuristic conflict than to supernatural monsters.
What distinguishes Paper Girls is its exploration of how people change over time, both physically and emotionally. Meeting an older version of yourself can be an unsettling experience, especially when the person you become challenges everything you believe about your future. The four protagonists must navigate these revelations while trying to understand a conflict far larger than themselves.
Despite its relatively short run, the series delivers imaginative science fiction built around recognisable human emotions. Its blend of retro atmosphere, mysterious technology, and coming-of-age storytelling makes it a natural choice for viewers seeking something that feels familiar without simply repeating the formula of Stranger Things. Like The Society, however, Paper Girls was cancelled after one season, leaving its larger story without a full television conclusion.
Which Sci-Fi Series Should You Watch First?
Choosing your next series depends on which elements of Stranger Things made the biggest impression on you. If you loved the slow-building mystery and the feeling that every small detail mattered, Dark is the strongest starting point. If you prefer supernatural discoveries and young characters uncovering hidden powers, Locke & Key offers an entertaining alternative. For viewers fascinated by scientific experiments and parallel dimensions, Fringe delivers a deeper, more expansive exploration of those ideas.
Meanwhile, The OA is ideal for anyone drawn to mysterious realities and philosophical questions, while The Umbrella Academy offers a more unconventional mixture of superpowers, family drama, and apocalyptic danger. The Society suits viewers interested in survival and the consequences of a world without familiar social structures, whereas Paper Girls is especially appealing to fans of nostalgic adventures and time-travel mysteries.
Each series approaches science fiction from a different angle, proving that the genre is not limited to futuristic machines or spectacular special effects. At its best, science fiction uses extraordinary circumstances to examine familiar questions about identity, family, friendship, power, and the consequences of human curiosity.
Final Thoughts: Finding Your Next Stranger Things-Level Obsession
The lasting appeal of Stranger Things comes from its ability to make the extraordinary feel personal. Its monsters and alternate dimensions create suspense, but its friendships, family relationships, and coming-of-age struggles give the story its emotional foundation. That combination is what makes finding a replacement so challenging: the next show needs to offer more than strange creatures or a mysterious scientific experiment. It needs characters and ideas worth investing in.
The seven series on this list offer different ways to recapture that excitement. Some explore the mysteries of time and alternate realities, others focus on supernatural powers or secret experiments, and several examine how young people respond when the world stops making sense. Their tones range from philosophical and unsettling to humorous and adventurous, giving viewers plenty of options depending on their mood.
If you want one recommendation to start with, choose Dark for a complex mystery that rewards careful viewing, or Fringe for a longer science fiction adventure built around strange cases and a gradually unfolding conspiracy. For something closer to the youthful supernatural atmosphere of Stranger Things, try Locke & Key or Paper Girls.
Ultimately, the best follow-up series is not necessarily the one that resembles Stranger Things most closely. It is the one that makes you curious enough to press play on the next episode, question everything you thought you understood, and return to its fictional world even after the screen goes dark.
