As a skydiver, yep the falling scene was fun to watch. not remotely feasable but well captured (good luck talking to anyone in freefall and i won't bother asking how the "i'll electrify your arm so you cant let go" bit worked). again its the fact it has good moments that make me more dissapointed with the overall film. i dont expect any type of reality from an iron man film but i do want some level of consistency with the two other films and the avengers since its mentioned constantly throuought IM3. we have had previously a fight between iron man and Thor which was hard fought though Thor clearly had the upper hand being a literal god and all. now we have Guy Pearce (go aussie) and his minions who can shred the iron man suit with no effort which is something the god of thunder wasn't able to do and why, because they are hot??. If it was a stand alone film no problem but it's not, it has 3 films worth of hstory behind it and contradicts a hell of a lot of what came before it.
Tony having the panic attacs because of the new york thing was a nice touch but nothing comes of it, it allows him to have a moment with an inconsequential character (the kid) who tells him to build something then he's fine the rest of the film. I dont care about the random kid he meets, he does nothing to progress the story, neither does ben kingsly but at least the argument there can be made that he's the macguffin of the film.
