Many of us know the feeling when there’s a movie announced that’s an adaptation of a novel or comic book movie that we know and love. And unfortunately there’s also many of us that know the heartbreak when that adaptation fails to live up to the potential of the source material. This list is about those movies that took a comic book and turned it into a mediocre movie, but it had the potential to be something great. Note, I am making this list based on the potential of the world and concepts that I can infer based on what’s presented in the movie, I have not read or am familiar with any of the original source comic books/graphic novels.
