Sci-fi shows have a nasty habit of being killed off too soon. By its nature, the genre is speculative and weird, meaning that stories are often simply ahead of their time or don’t appeal to audiences on release. Some of the best sci-fi series ever were axed after just a season or two (or even a handful of episodes), leaving their small but devoted fanbases hungry for more. This makes these shows prime candidates for remakes. Reimaginings of these shows could give them the conclusions they deserve, or even just enliven them with modern graphics.
