In Iron Man 2, Tony talks about manufacturing world peace but we never see it. There actually felt like there was less action in Iron Man 2 than in the first movie and I didn't think that was possible.
Yeah, one of the huge flaws with IM2 was that there were barely any Iron Man action scenes. We got way more and better done Iron Man action scenes in Avengers than we ever got in IM2, even though that movie had an entire team of superheroes!
