“You’re nothing but a boy, trying to prove himself a man,” says a villain in Marvel’s latest swing for the fences, Thor. It’s directed at the titular character, but actor Chris Hemsworth seems to take this challenge personally, spending most of the remaining film convincing the audience that he can be a leading man, with a substantial emphasis on the M-A-N. He growls and bellows, and furrows his impressive brow, all with the intention of out-manning whatever other men happen to be in his company. For the most part, this is what superheroes movies are about: visceral displays of machismo that make an audience want to holler and cheer. If that’s the goal, then Thor is a hearty victory.
