The story line was not very engaging and didn't have the heart of the first movie. I thought by having Marvel develop their own movies, the characters and plot would live up to the standards in their comic books but this was not the case. Robert Downey Jr. needs better dialogue to work with to fully exploit the dimensionality of Tony Stark and his acting ability. At times, his 'bad behavior' was predictable and cliche– the drunken, narcissist billionaire routine is getting old. Didn't feel the chemistry between Pepper and Tony. For Iron Man III, I hope they can find something other than robots for Tony to fight.
