Well, it was not pretty darned good I'd say. Againt the "with great power comes great responsibilty" theme rears its head. I thought that was done to death in the Spiderman series. Also, what's with the same tired old "fear of people that are different" storyline? Didn't they do that for the first two? Shouldn't we move along to something like "Oh my god! There is a big bad enemy terrorising the country... We should call the X-Men".
Don't get me wrong, the old theme is not bad, however, we saw more than enough in X1 and X2.
As for characters... So many, so few explanations. I know they are making a Wolverine prequel, but we know more about him then colossus, or ArchAngel, or Kitty. Should we not develop those characters a little?
Besides all that, good action, fun to watch special effects and some great acting by the principals. Gotta go with 4.
