Thor

Thor: The Jotuns must pay for what they have done!
Odin: They have paid, with their lives. The Destroyer did its work, the Casket is safe, and all is well.
Thor: All is well? They broke into the weapons vault! If the Frost Giants have stolen even one of these relics...
Odin: They didn't.
Thor: Well I want to know why!
Odin: I have a truce with Laufey, king of the Jotuns.
Thor: He just broke your truce! They know you are vulnerable!
Odin: What action would you take?
Thor: March into Jotunheim as you once did! Teach them a lesson! Break their spirits, so they would never dare try to cross our borders again!
Odin: You're thinking only as a warrior.
Thor: This was an act of war!
Odin: It was the act of but a few, doomed to fail.
Thor: Look how far they got!
Odin: We will find the breach in our defenses and it will be sealed.
Thor: As king of Asgard...!
Odin: BUT YOU'RE NOT KING! Not yet.

"A wise king never seeks out war. But - he must always be ready for it." I like the antiwar message of this movie and the way that Thor has to learn humility and compassion. He has to learn to be grateful for what he has and to treat other people with dignity. He shows as much when he offers to sacrifice himself to save his friends:

Thor: Brother, however I have wronged you, whatever I have done that has led you to do this, I am truly sorry. But these people are innocent, taking their lives will gain you nothing. So take mine, and end this.

No, it's not OK to kill frost giants just because they're different from you. It's not OK to kill innocent people because of the actions of a few radicals. The arrogant Thor from the beginning of the film reminds me of the the wicked Nephites who gloried in their own strength and craved battle. They got it in their heads that they could take the fight to the Lamanites. Big mistake.
Directed by Kenneth Branagh and written by J. Michael Straczynski? Sweet. Also got me interested in Norse mythology.
