When it comes to science fiction franchises, Disney doesn't have the greatest track record. The studio's Star Wars content has been heavily criticized for a decade now, and other projects like Tomorrowland, A Wrinkle in Time, and the Tronseries never made much of a dent or garnered a big fanbase. However, perhaps the biggest sci-fi tragedy in Disney's entire catalog is 2012's John Carter, which adapted the long-beloved works of Edgar Rice Burroughs to the big screen. With Taylor Kitsch playing the leading John Carter of Mars, the film was supposed to spawn a trilogy that would have continued these intergalactic adventures. Unfortunately, poor marketing killed John Carter before it had the chance to jump too high off the ground — but what would the sequels have been like? From what we can tell, they would have been magnificent.
