Okay, I pretty much liked the movie. It had a good beginning and an awesome third act. Two points bugged me about it. First, Loki was kind of a weak villain. Ultimately, he comes off as a jealous, spiteful child having a temper tantrum, Secondly, the move stops for about twenty minutes during act two. I mean, it was kind of bizarre. You had a decent first act with the presentation of the threat and the gathering of (most) of the team. You then had the near-obligatory hero fight that reintroduces Thor, And then the movie just kind of loses power and rolls forward only under the personalities of the people there, and by people there I pretty much mean Robert Downey Jr. and Sam Jackson. And then, very much like the absurdly design-flawed SHIELD headquarters, the movie sputters back into life and kicks into top gear through to the end.
