Iron Man 2 fell quite short of its predecessor. You still have the charisma and strong performance from Robert Downey Jr. And Scarlett Johansson and Samuel L Jackson are a welcome addition. But the plot is flimsy at best. The main antagonist is weak and unimpressive. Mickey Rourke's character's motivation is quickly explained in 30 seconds and the start of the film offered little context or explanation and now he's the main threat? He was so unimpressive that he should have been someone Ironman wiped out in the first 5 minutes. The action scenes, court proceedings to seize Tony's technology and his poorly executed relationship with Piper is also not particularly exciting to watch.
