Robert Downey Jr. once again does a really great job playing the super narcissistic Tony Stark who has privatized world peace with his Iron Man suit. He has problems with his heart again, and he is in desperate need to come up with a new energy source. At the same time more or less evil forces from all sides try to get hold of a copy of the Iron Man suit for various reasons.
The interaction between Tony and Pepper (Gwyneth Paltrow) is just as great as in the first movie. Scarlett Johansson is fine as the ass kicking super agent Natasha Romanoff and Mickey Rourke does an excellent job as the supervillain Ivan Vanko.
The story is not bad and there is plenty of excellent special effects. The movie however isn't overloaded with effects and there is plenty of room for great one liners and jokes.
Keep watching thru the end credits to see the last scene that reveals that the story isn't over yet.
