After watching this movie I'm still not sure what the plot is supposed to be. Is Tony Stark trying to save the world, discover who he is, avenge his friend, save his girlfriend or unravel a sinister plot? None of these themes was developed at all and nothing really holds this movie together or drives the main character forward. Another huge problem is that there's no real antagonist until the last 15 minutes of the movie. Sure, we see clips of some maniac blowing things up but there's no conflict between the good guy and the bad guy until the last few minutes of the film. This film left me feeling empty and disappointed. I'll just have to wait for Joss Whedon and Avengers 2 to get Iron Man right again.
