4 out of 5 stars.

Iron Man 2 is a fun sequel. It has some fun action sequences. Bigger climax. But the fight with Iron Man and War Machine against Whiplash was a bit short and weak. The cast ensemble was good. Tony stark faces a conflict within that is affecting him. The film does have a uneven pace in the middle of the movie. Scarlett Johansson shines as Black Widow. There is a great post credit tease scene. Besides the slow pacing with Stark facing his own issues that causes him to be irresponsible. It is a fun sequel worth watching.
