I just stepped out the theater and here’s what I’m thinking:
Tony Stark was supposed to have been undergoing some kind of issue that may or may not have been discussed in the past and it has to do with how he cannot sleep. I think there may have been a story somewhere there and they should have pursued that, a kind of ‘he is not as infallible as you think’, always compelling with superhero stories imo, but for some reason they didn’t.
Or maybe they did, but at some point during the movie a villain appeared, (the guy who played the king’s brother in ‘The King’s Speech’), and there started a story around him as well as a girl (she played Ben Affleck’s girlfriend in the excellent ‘The Town’), but it wasn’t really interesting, didn’t make sense, or both. At any rate I felt I was being distracted from what I really wanted to know – what was wrong with Tony Stark and how was he going to deal with it.
