As do fans. I don't know that I had a preconcieved notion of what would happen, but I thought it all went fairly well.
You also missed the Hulk vs. Thor stuff, which also went pretty much as I'd have expected.
It is a challenge when you've got, on one side, guys like Iron Man, Hulk and Thor, and on the other side, Captain America, Black Widow, Nick Fury, and Hawkeye. I mean, I know that the Avengers has kinda always been like that, but its a little hard to make challenges for such a diverse team seem challenging for the first group without being completely overwhelming for the second, or challenging for the second without being a complete cakewalk for the first.
