The Best Sci Fi Television Series of All Time

List Criteria: Sci-fi TV shows and series with science fiction elements

A list of the best sci-fi shows and best sci-fi series of all time, as ranked by hundreds of Ranker voters. This list includes long-running sci-fi TV shows like Doctor Who as well as some of the best cancelled shows of the genre. Science fiction TV shows have been around for decades, and some of the longest running shows have fallen into this category. Popular shows such as Star Trek have enjoyed several incarnations, and fan-favorite shows like "Firefly" and "The X-Files" have made the crossover from TV to the big screen.
