List RulesVote up the science fiction and fantasy television series airing new episodes during the 2020 calendar year that offer galactic levels of excitement.

Are you into exciting sci-fi TV shows and want to see what's new in 2020? These are the most exciting science fiction TV series available to watch in 2020, which are either new or continuing from a previous season. For a science fiction series to be truly exciting, it has to be the kind that depicts more than just cool new tech, it has to show a conflict between one or more groups of people, aliens, robots, or whatever in which survival is key. Exciting science fiction involves plenty of action and adventure along with the standard aliens, space voyages, time travel, and alternate universes.

Some science fiction series such as Star Trek: Discovery and Picard pick up where prior Star Trek series left off, taking us across space and into the future with well-developed characters and plot lines. The Orville might be a parody of Star Trek series, but many fans think it's an exciting enough show that it can be counted as one of the best (not) Star Trek series ever made. Netflix's The Boys tackles superheroes, Amazon Prime's Westworld is all about androids and AI, and Man in the High Castle delivers an exciting and terrifying vision of an alternate timeline that would have changed the course of history. 

Which of these exciting sci-fi TV series are your favorites? Which are you most looking forward to in 2020? Vote up your favorites and watch as the most exciting science fiction rises to the top!
