Hmm, I can see your point. Personally I watched it once on dvd on a big flat-screen instead of my smaller computer. I agree with that the film should more chaotic and brutal. But I think we're going see more of that in Avengers 2, where it seems they're going to introduce a more powerful enemy who's obsessed with death. Maybe there's also more room for developing the characters' relationships. I would like to see more of that.
