I'm a little wary about focusing the movie more on Tony Stark if I'm being honest. Downey was great in the role in the first film and in the Avengers but Iron Man 2 relied too much on Tony's wacky antics and failed miserably on a creative level. The villains were nothing short of pathetic, with Rockwell's character only being there to make Tony Stark look good in compariosn. There was also the waste of time "I'm dying" storyline, which was something the ultimately brought nothing to the story. They missed their chance for Demon in a Bottle as well.
