I am not saying they are Marvel Zombies. I am saying in general the fan community looks to specifically nitpick and complain with this franchise, because of past frustrations (namely X3 and Wolverine Origins), and because Fox makes them as opposed to it being "in-house."
This is not so much pro-Marvel, as anti-Singer/Fox. Because no, I do not think these are any worse or more of a deviation than Scarlet Witch, Hawkeye, or Nolan's Batman (or especially any of Nolan's villains who despite being brilliantly realized on screen, sans Talia, mostly look only faintly similar to their comic book roots). But because of who made this movie, it is more of a problem for online fans. Meanwhile, if they had returned to the yellow/blue jumpsuits from First Class (which I did love), fans would probably bring up how they weren't individualized.
My point is people will complain about these movies no matter the choice made.
