Ultimately, none of the shortcomings are really surprising. Iron Man simply continues the tradition of many movie-based games that have come before it. The sad part is that there was an opportunity here to do something interesting with a truly great comic book character, but instead we end up with something that's merely passable as a video game.
Pros: Robert Downey Jr. does a decent job; the Iron Man character model looks OK.
Cons: Generic and boring visuals; ridiculous difficulty curve; weak controls.
