Science fiction on television has taken us everywhere—from alternate histories and time loops to artificial intelligence and virtual realities. But the best of the genre know that no matter how wild the premise, truly compelling sci-fi is always rooted in human stories. As technology becomes more woven into our daily lives, these shows use futuristic concepts to explore timeless human choices.
Over the last two decades, TV has delivered some of the most ambitious sci-fi ever made, pushing imagination while staying grounded. Whether imagining a perfect utopia or charting humanity's future among the stars, here are the most perfect sci-fi shows of the last 20 years, ranked.
10. 'Bodies' (2023)
One murder mystery is complicated enough. But when four English detectives from four different eras find the same dead body in the same alleyway, something is clearly off. Bodies is a trippy take on the bootstrap paradox—an infinite time loop that seems to go on forever. Each detective uses their own methods to uncover the killer and break the loop. The thrill lies in seeing police work across four periods, and the discrimination these detectives face in their respective eras, which only complicates their work. From 1941, when Jews were heavily marginalized, to 2023, where being a Muslim in racially charged England is still a reality, Bodies is both solid sci-fi and a commentary on societal beliefs.
9. 'Years and Years' (2019)
Set over 15 years, Years and Years follows the Lyons family as the world around them crumbles under authoritarianism and rising anti-immigrant sentiment. With populist leader Vivienne Rook (Emma Thompson) driving the nation through fear and hate, it's people like the Lyons who are pulled apart during a global crisis. The genius of Years and Years is that dystopia doesn't happen overnight, giving the show its realism. Fifteen years ago, people wouldn't have imagined talking to an AI through a phone screen, yet here we are. Like real life, technology in Years and Years slowly blurs the lines between objective and subjective truth to fuel political means, thanks to deepfakes and hoaxes.
8. 'Night Sky' (2022)
Most sci-fi focuses on young heroes confronting the unknown, but Night Sky takes a different approach by placing an elderly couple at the center of its mystery. Irene York (Sissy Spacek), a retired teacher struggling with illness, and her husband Franklin (J. K. Simmons) live a quiet life in rural Illinois. Hidden beneath their shed is a chamber that transports them to a mysterious, deserted planet. Though it lasted only one season, Night Sky proves that sci-fi belongs to everyone, showing how ordinary people respond to the extraordinary. While younger, more tech-savvy characters might focus on understanding the mechanics of the unknown, Irene and Franklin approach it with empathy, resilience, and a deeply human perspective. In doing so, Night Sky suggests that compassion matters far more than youth or technological expertise.
7. 'Black Mirror' (2011–Present)
Black Mirror immediately took the world by storm with its infamous pig-intercourse scene in its debut episode. If that's any indication that the anthology series isn't afraid to push boundaries, it does its job well. Each episode tells a different story set in a world shaped by emerging technology, from virtual reality to simulated worlds. But for all its hard tech, Black Mirror is really about how technology exposes the uglier side of human nature rather than making life easier. Whether it's a memory implant that allows someone to replay every interaction with his wife or a digital afterlife used to overcome mortality, the series repeatedly shows that technology comes with consequences. At its most extreme, those consequences can even lead to death.
6. 'For All Mankind' (2019–Present)
No other show commits more to the alternate Space Race plot than For All Mankind. Set in a world where the Soviet Union beats the United States to the moon, the series prolongs the space race with even higher stakes. The moon is no longer the objective, and these astronauts have their sights set on building life on Mars. With each season set in a different decade, For All Mankind shows how changing eras affect not only the technology required to send people into space, but also the emotional toll on its astronauts, engineers, and their families as they grapple with ambition, loss, aging, and the sacrifices required to push humanity forward. And with every breakthrough comes a new set of political and societal consequences that can either empower humanity or expose its darker impulses.
5. 'Pluribus' (2025–Present)
Pluribus is a recent addition that has already made waves. The series explores a world where multiple realities coexist, and a group of unlikely heroes must navigate the chaos. Its blend of high-concept sci-fi and character-driven drama has earned it a spot among the best.
For fans of the genre, these shows represent the pinnacle of what sci-fi television can achieve. They remind us that even in the most fantastical settings, it's the human heart that makes a story truly unforgettable.
