Re: Oh come on Spock, it sucks! Big Deal. (SPOILERS)
I was talking character arc. The movie starts with "Look, Kirk is still immature." and ends with "Look, Kirk gets his 5-year mission." but in between, there is nothing that makes him earn that.
I disagree. I thought there was, quite a bit. Kirk's realisation that his desire for vengeance was rash. His realisation that he's no good as the captain. His sacrifice, etc.
And that's my opinion.
