There were a lot of problems with Iron Man 2. But one of the biggest was in its choice of villain. Jeff Bridges' Obadiah Stane worked perfectly in the first flick as the dark mirror to Tony Stark's hedonism. Unfortunately, old shell-head doesn't have the best rogues gallery in comics. The sequel pulled out evil industrialist Justin Hammer, played by Sam Rockwell, and it just fell flat. Hammer is a second banana in his own grand scheme, and his presence just means less time for Mickey Rourke's Ivan Vanko.
