At least with Hulk they attempted to make a quality movie with depth and character. The director tried things. Some scenes are quite gorgous to look at.
With X3, they didn't really try. That movie rushed through scenes. The dialogue was terrible.
Storm: Hank, I like what you've done with your hair.
Hank: I like what you've done with yours!
Then theres this awkward moment where she touches her hair. The whole movie felt awkward. The actors literally had nothing to work with. Nobody had any development. Angel - what was the point? Beast - A character that had more screentime than most - absolutely no development. Scott - dies off screen.
What was the point of Wolverine going to the forest? Wolvie is in the mansion, then he's in Magneto's camp, gets in a pointless fight, gets beaten by Mags, then he's back in the mansion. Is Mags' camp like 5 minutes away from the mansion?!
The movie has a horrible pace.
