He tries to protect a boy who is going to become dangerous, mostly by being worse at it than everybody around him.

The sequel is louder and more crowded, and its best joke is a team assembled at enormous expense and disposed of in ninety seconds. Under the noise it is about somebody who has lost the thing that made him want to live and keeps failing to die.

It also introduces the character who lets these films eventually reach the shared universe, though nobody knew that at the time.
