I wouldn't be too sure of the whole rejoicing thing. Thus far, I can't say that what we have so far is worth talking about. None of the marvel comic adaptations have been able to hold a candle to DC's Batman, with the exception of Iron Man. Iron Man 2 was alright, but not as good as The Dark Knight in terms of sequels. The rest of the offerings are meh. I do enjoy the campiness of the X Men but pt. 3 was awful, and Wolverine Origins was embarrassing IMO.
Spiderman 1 was fairly decent, with good character development and such, but performances were stunted because of stupid reasons.. like the fact that what's her name stinks *can't remember the name of the girl that played Mary Jane for some reason*.
Hulk in any of its forms is HORRIBLE. They could have been great given a good plot and direction. Edward Norton walked into a complete cluster F on that one, and he is actually ideal for that role. Eric Bana, while a good actor, just didn't do crap with it, and that whole movie was just a cheesy mess. Not even my super hot girlfriend Jennifer Connoly was able to distract me from it!
As for the other Marvel movies, they are SO not even worth mentioning!
