Hopefully Matthew Vaughn takes it back from him and rights the wrongs of Bryan Singer. Left X3 to make one of the worst Superman films of all time, made Wolverine the focus of the X-Men because Hugh Jackman, and now is making Mystique the focus of X-Men because overhyped Jennifer Lawrence.

He killed one of the most important X-Men characters in 1 (Senator Kelly).
He made Rogue not really have any powers (No Superhuman strength and flying)
He also let Rogue get cast by a very unattractive untalented actress (Rogue is supposed to be attractive)
He didn't have Henry Guyrich and Master Mold in Days of Future Past
He didn't have Bishop as the main character of Days of Future Past (who actually went back in time in the comics)
He didn't have Gambit in the X-Men universe (One of the most popular members of the X-Men with Wolverine, Jean, Cyclops, Beast, and Rogue)
He also had Cyclops do nothing more than be a c*ckblock to Wolverine, rather than actually being a character

Has the X-MEN not really be a team by focusing on only Wolverine and Mystique, rather than the team as a whole, and the issues they must overcome in a society that won't accept them. (What the X-Men is supposed to be about).

I'm sure I can find more issues with these films, but they aren't having any justice done by being made by someone who has no respect for the comics at all.
