There's been a lot of talk lately - not least in articles here on WhatCulture - about the differences between comic book movies and the very comic books that they are based on. Some of these differences are very subtle and some are massive, some are done for artistic reasons and some are done seemingly for the sake of it. Either way, there is an abundance of these changes and, while some have been welcomed, some we could definitely have done without. So I thought I'd put together a short list of some of these major changes, as a talking point, and see which other changes caught your eyes for whatever reason. Here are twelve massive changes from the source material in comic book movies... N.B. I should point out that these aren't complaints (well, not all of them), they're merely observations.
