Iron Man has all the best parts of the character on screen imo. The action was thunderous and you felt it. The suits felt big, clunky and believable tech, made by a genius with the resources. Tony was a *****e then redeemed and that was that, he didn't need to keep going back to *****e then good guy over and over again in the movies. The other movies did right by the supporting characters but not by Tony and the suits imo.
