There's really nothing to the "arrogance" thing in Thor
; the entire affair as far as the characters are concerned is paper-thin and perfunctory. Same for Stark; Downey's charm and performance carries the superficial and predictable "arc."
I mean, there are
movies released every month in which character and character evolution matter and are treated with some observational acuity if nothing else - but these are films made for grown-ups and don't involve people in costumes flying and throwing things.
