I believe X-Men 2 remains my favorite of the series, but this movie is now at least a close second. It suffers from some of the standard problems of the series (How many immensely massive objects does Magneto need to prove he can levitate?), but it had characters I could care about, actions that were relatively believable, and moments that I would just like to see again. One particular pickpocket turns out to be a scene-stealer as well.
I don't know if I should have brought Connor to see the movie as well as Trevor, but he seemed to do pretty well with it. His favorite X-Man? Wolverine, of course. There are some disturbing images through the movie as a portion of it is in a dystopian future. Perhaps I should be concerned that he didn't seem bothered by it. Trevor, meanwhile, had his hands covering his eyes through quite a few parts (I think Mystique's scenes were what really got to him).
Like anything dealing with time-travel, I have some questions and concerns about both the method and the "rules" that they established for it. They make sense for the cinematic aspect, but not when I try to apply any level of logic to them. Alas, I have yet to find the time-travel movie that satisfies its own internal logic.
All said, I am certainly willing to go see the movie again. Let me know if you need someone to see it with you.
