9. X-Men Origins: Magneto
The X-Men franchise has undoubtedly had its fair share of ups and downs, never quite reaching the greatness of Bryan Singer's first two films in the franchise. Though they don't quite age well when compared to the slew of current superhero tales, they're far better than films like X-Men: The Last Stand and X-Men Origins: Wolverine. Fox's decision to create spinoff prequel films featuring several X-Men characters was flawed from the start, and quickly abandoned once Origins: Wolverine infuriated geeks everywhere and became one of the worst comic book movies ever made. However, one project that had been in development that may have been great was an origin film featuring a young Magneto. David S. Goyer was brought on to write and possibly direct the film, which quickly hit roadblocks after the writer's strike in 2007. The project was touted as being "X-Men meets The Pianist," and would have centered around Magneto exacting revenge on the Nazis before meeting Charles Xavier, and the friendship that soon followed. Before long, their differences would begin to show and the two would, inevitably, come to a crossroads. If that at all sounds familiar, that's because they took those ideas, broke them up a bit, and used them in X-Men First Class. The first act of that film, featuring Michael Fassbender hunting Nazis across the globe, is arguably the best part of the movie, and a Magento origin would have expanded on those ideas. The film we ended up getting was good, and succeeded in rekindling interest in the series, but it's not without its problems and maybe this more focused take would have been an improvement.
