I found it ironic, that while I did like Iron Man, it had WAY less action than I thought it would, it definitely had less than Ang's Hulk. The difference I think, was that while Ang's movie had no comedy whatsoever, Iron Man gave Downey alot more "character-wise" to work with, and alot of it was funny. If you really look at it, Iron Man had less action than Batman Begins & Spiderman 1 also, but the stuff outside the suit was a little easier to digest while your laughing, I suppose.
On the second viewing of IM, it really seemed to take longer for things to happen, maybe because I already was anticipating my favorite scene (the terrorist attack of course) but even the action scenes themselves weren't terribly long. I think IM will be like Spiderman 1 in the future, where people look back on it and realize it may have been "slightly" overrated. Now I'm no hater, and I'm not saying that because I want Hulk to be more successful or anything childish like that, but when you compare the critic reviews of IM to almost all other superhero movies that we would consider good, it would lead you to believe that IM is the best superhero movie ever made, and I really disagree with that.
It seems as though, as long as you throw in a lot of jokes, the critics generally will love your comic book movie (in most cases), but if it's serious in any form, then the movie isn't embracing the inner "goofiness" of its roots like they think it should, so they hate it. I feel like some heroes lend themselves to comedy, IM and Spidey being good examples, but certain characters just aren't made to be that funny, Batman & Hulk being two of them. Pick up either one of those, and there just ain't a whole lot of lighthearted stuff in there, even if it is a "comic book," so instead of these critics turning up there noses at comic movies they deem should never take themselves seriously, maybe they should purchase a few classic stories and get in tune with the actual themes, I mean, these movies are here to stay for the forseeable future, maybe a little research wouldn't hurt. It may not be Shakespeare, but it certainly ain't Seinfeld either...
