The X-men isn't just social commentary doing just one aspect well isn't enough. Fox didn't care about the general storyline of the franchise, Fox didn't about characters major characters like Sabertooth, Colossus, Storm, Kitty, Jubilee, Nightcrawler not being 2 dimensional side characters, They were shame of the comic book aspects like costumes, cosmic elements or silly family connections,They though storyline and characters where interchangeable,etc.
In reality they just wanted do "Heroes" style superhero story heavily grounded in reality just enough elements of the comics to make a fan take a look at it. X-men name was just bait fans while they use the property characters as toy box for writers to attach general scripts to it. I am not saying I am completely right that how I feel about the movies. Something like X-men First Class for me was a good movie but a bad X-men adaption.
Nobody is saying movies have to be one for one retelling of the comics, The Avengers and most of Marvel movies aren't that but these movies carried the spirit of the comics and they weren't ashamed of the source material(except Thor 1).
