I saw X-Men over the weekend and... I didn't hate it.
Of course, I saw it for free, so mitigate my feelings on the film to whatever degree you think appropriate. But it's pretty cool-looking, I found the character stories to be fairly interesting, and I enjoyed the dialogue.
One thing I hated about the movie speaks to a larger issue I have with movies in general. I can't ever remember a time when filmmakers were more blatant about leaving their films open to sequels. Back in the day (Star Wars, Raiders...) films used to be stand-alones... and if a sequel became appropriate, they found a way to link one to another. This one, however, has a storyline that just plain peters out right in the middle. There's almost an arrogance to it, like they know we're gonna come back, so they don't bother finishing the tale. So, that really pissed me off.
However, in an era of film when everything has to be complicated, or drawn-out, or clever, or a twist, this movie is refreshingly simple at an hour-and-a-half. For a good example of a film that's not trying too hard, check out the scene where one character must prove to the others that he is who he says he is. His solution is simple, to the point, and damn funny.
Suggestion for part 2... find a way for Cyclops to be able to shoot his killer eye rays without having to pull a trigger every time.
