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

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.
