I say "almost" because, while Spock's very central (hell -- he's the one who saves Earth, while Kirk just saves Captain Pine!), Kirk's the one who goes from "delinquent" to "captain," and also the one who really propels them to victory. (It made me think of Blood Diamond, which in structural terms makes Djimon Hounsou's character the center, but all of the active protagging in the plot belongs to DiCaprio's character. Though not as unbalanced as that one.) But I think that's why I want to see more: I think the writers really could do good things with the dynamic between the two of them.
