Lacking anything else to do, I went to see this last night.
It was way better then the reviewers said. Way!
A good summer time movie, I enjoyed it.
It was a mix of humor, emotion, action, and there were some pretty important issues/themes imbedded in the story, albeit in an over-the-top, superhero style. The reviewers had some conceptual trouble with the fact the movie takes place in the past, in between a couple of the older X-Men movies. I thought this was one of the cool things about movie - it gave opportunities for the audience to "participate", to say to themselves, "Oh, cool, I know where that's headed".
The 3D was cool (meaning well done). The only "in your face" 3D effect was when Jean Grey walks on thin air out over the edge of a building - she walks out of the screen into the audience. I smiled.
Hey, The popcorn and soda was decent, too.
