I liked it better than the first. I also liked the little romance glitches between Rogue and Iceman, but I liked the tension between Jean, Cyclops and Wolverine much better - it is more mature and more complex. I am not used to seeing Rogue with Iceman - she eventually falls for Gambit...
I also really liked how they showed Jean's alter-ego, the Phoenix - which is, in short, the super psychokinetic and telepathic manifestation of Jean, but she does not really have the same "life" as Jean, and if she is to come back in X3, she will be like Wolverine: innocent to her past, and only knows of herself as a person who is living "today," with no history, no past connections...nothing. Even her relationship with Cyclops she will forget, or at least, will posses very small, weird recollections left of it.
I really did not like some of the combat sequences, as they were very poorly produced, compared, for example, with The Matrix 2, which they previewed right before X2. The distinction we can make concerning the production of these two movies are numberless. The Matrix 2 is so much cleaner than X2, and that is the most obvious, and more important, note I can make.
It was fun, but nothing like The Matrix. They haven't really played out the drama well: X-Men really has a lot of psychological insights to the human emotions and human conduct, but the movie fails to show these on their proper levels. The directors might be not very motivated or spirited...
