Gotta agree with this. It is interesting that some cite Tony himself not being peril himself as reasons for not liking an action scene they really enjoyed just seconds beforehand, calling the suit a drone as if it was Jarvis saving those people not Tony, that Tony was just chilling on a boat with a tropical drink in hand while the suit did everything. The story ran with the idea of how Stark and his armor relate in various ways, physically & psychologically, starting with the telekinetic combination of the MK42 and the suits for all seasons, stripping all that away and ending with the destruction of the suits and removal of the "machine" from the man, arriving at the idea that he doesn't need the armor to be Iron Man. I can see how some don't like that direction or idea, especially if they had a hard-on for a Kingsley Mandarin fight.
Eh, to use your analogy, I had a hard on for a good movie but what I saw left me limp. That's just my opinion, maybe others found it to be a great ****.
