There's only one way to fix the X-Men problem.
Seriously though, if look at the X-Men films as just superhero films, they're really great, especially X-2, FC and DOFP. However, when you look at them as 'X-Men' films, you'll lose it. I said it in my DOFP review, what really bothers me Bryan Singer's seemingly boundless ability to misinterpret the true spirit of the X-Men comics. He still misunderstands some of these characters. But unlike other directors from the past who have butchered comic book adaptations, Singer's interpretation of the characters makes you question the changes that were made especially if you're a hardcore X-Men fan. Because to me, at times it felt that Singer was trying to hard too appease the fanboys and detractors who have not been pleased with how he has handled the X-Men franchise and completely missing the point of what truly makes the X-Men who they are.
I think a lot of people don't understand why some people are very critical of the X-Men films from a fan's pesperctive. If you go read Uncanny X-Men, Ashtonishing X-Men etc and come back and watch the films, you'd want Singer fired and never want him to touch any other CBM ever. That being said, when it comes to story telling, he's great and that;'s what so frustrating about it. maybe if he actually paid a lot more attention to the source material, he wouldn't be saying statements like these. I basically let go, after 14 years of complaining and with little to know change, I just accepted the way these films are. If I want my X-Men, I still have my comic books. I'm excited for Apocalypse though.
