12 Best Sci-Fi TV Series

By Vlad Zakh · March 10, 2026

Black Mirror and Westworld use science fiction as a lens on something much closer to home, Battlestar Galactica and The Expanse go harder and more political, and Severance shows the genre still has genuinely new ideas. Foundation adapts Asimov’s story of a mathematician who predicts an empire’s fall, The X-Files pairs a believer and a sceptic at the FBI, Dark turns missing children into a multi-generational time-travel puzzle, and Fringe connects odd science to a parallel universe. Doctor Who, Stranger Things and The Man in the High Castle round out the list.
