Not to add more negative comments, but one thing I didn't like about Pine is his voice. Even if I don't compare him to William Shatner, Pine's voice sounds like a kid and somewhat irritating.

It sounds odd to hear him say the signature Kirk lines such as: Kirk to Enterprise, Kirk to engineering, Scotty! Or to hear him say Bones. Sorry Scott, I didn't hear what you heard.
Perhaps if the next film, he will play him a bit more matured, his voice will also lower or be less irritating, it will work better for me. Other then that, I will give Pine some credit for doing a pretty monumental task of taking on the role of Kirk.
I did see the piece on Pine in the special features and the one Kirk mannerism is the way he crosses his legs in the chair, and he talks about that. Pine
I watched Balance of Terror the other night and it was to me, one of the best episodes of TOS and Kirk at his best. This and Corbomite Maneuver, the first series episode, Shatner is Kirk!
