Best sci-fi TV shows of all time
Our best sci-fi TV shows of all time list.
When a sci-fi concept is brought to life on TV, there’s a lot of opportunity to succeed, expand, and delight viewers with multiple seasons, recurring cast members, and dedicated writers. Sometimes, TV shows don’t get that lucky, getting canceled before they’ve had a chance to truly shine. But, that doesn’t mean they don’t deserve a place on our list. Earning cult status as a TV show is just as impressive.
Whether it’s ten seasons or one, the beauty of a TV show spanning multiple episodes means there’s hours upon hours to get creative. And, with the sci-fi genre, the possibilities are seemingly endless. Whatever weird, wonderful, and wacky ideas that can be dreamt up and pitched to the right people mean viewers eventually get a chance to experience these alternate realities from the minds of geniuses.
Our list of the best sci-fi TV shows of all time spans decades, explores galaxies, tests limits, and in some cases may even divide opinion, but we promise to explain why each of our 15 picks deserves its place here.
Whilst the best sci-fi movies get a feature-length slot on the big screen, sci-fi TV shows must captivate the viewer for hours on end, enticing them to watch every episode whether anthology-based or an episodic timeline. Our list contains a little something for everyone.
