I agree. I was a bit surprised how well it worked considering how many characters, but they do have some experience with it by now. I do have some CGI action fatigue, but this movie is no worse than any other special effect extravaganza in that regard. If you want what Marvel offers, this movie delivers a super-size scoop.
Edit;
Having thought a bit more about the movie, I think I like it better than this might have come across. It is actually amazing how they manage to pull off something of this sheer scale. My grievances are mostly about some of the special effects.
@Scotch_Lufkin: I am happy to report that this movie DOES NOT have too much Spider-Man.
