Collider has published a list of ten science fiction television series it considers essential viewing, spanning decades of the genre from early 1960s British television through to modern streaming-era productions. The list is framed as a foundational guide to the genre, highlighting shows that have shaped its tone and style and influenced much of what followed, making them worthwhile even for viewers who don't typically enjoy sci-fi.

Featured entries include the BBC's Doctor Who, recognised as the longest-running sci-fi show ever thanks to its "regeneration" device allowing new actors to take over the lead role; Netflix's German-language time-travel drama Dark, praised for its complex, twist-heavy storytelling; and 1990s American cult classic Babylon 5, noted for pioneering a serialised, novel-like five-season story structure. Other shows mentioned in passing include Battlestar Galactica, though the full ten-show list extends beyond the excerpt provided.
