One of the things that stood out the most to me while watching it is that outside of the 4 or 5 main stars Fox really doesn't care anything about the X-Men's supporting cast. Take Angel, a founding member of the X-Men known for his playboy disposition and heroic nature. In this he's a drunken pit fighter. Psylocke, long time X-Man and sister of Captain Britain, is hired muscle, a horseman of Apocalypse and one of like two characters that doesn't have a redemption story. Caliban, the Morlock who is so scared of his own shadow he actually makes a deal with Apocalypse so he can have actual powers that matter, is portrayed as some sort of underground power broker.
Also, Charles sure is forgiving of Magneto for killing all those people he kills in every movie.
I think this is one of the reason fans were so quick to embrace Deadpool. They actually made Colossus Russian. Who'd have thunk it?
I'm not advocating Fox give up the movie rights to the X-Men (even though that would be great) but maybe it's time to give the franchise to someone other than Bryan Singer. X-Men and X-2 were great movies, he's done as much as he can do right about now. Time to get someone in their with a vision for a simpler less confusing X-Men universe that knows why these characters have been so popular for so long. Maybe see what that Deadpool guy is doing for the next 10 years.
