I found it to be good. Not the best out of the 3, but good. I found that the whole "Cure" thing is overplayed, and if they bring it back in the next movie, it will be rediculous. First step, completely new plotline.
The cure better allow regain of all powers, since rogue is supposed to 1. Fly and 2. Have super strength. The whole idea of the little kid having the power of the "cure" was a cool idea, and really done well. HOWEVER, the movie was way too short and there was no background knowledge or any exstensive fottage about the kid mutant.
The moorlocks were also lame, and i feel that producers are just trying to shove as much special effects as they can into one movie, and in X-Men, that means giving lame powers to random mutants. They should have alos talked about how the Juggernaut was Xaviers brother. But No. They make him a complete idiot who babbles on about nothing and becomes a completely pointless character.
The scene between iceman and the flame dude (can't remember his name) was rediculous as well. Could have turned into one sweet scene, but they just pulled out a DBZ scene and blasted each toher for 30 seconds.
All in all, it was a good movie, don't get me wrong. But they better do a much better job in the next movie by bring in gambit, actually KILLING off characters for good, no BS about Xavier coming back to life after the credits. And bring in some badass dude, like Apocolypse. Fuck yeah, my rant for tonite. Peace
