With a future film, I'm guessing they can't just reverse course and make Kirk into something like the reserved commanding figure from BALANCE OF TERROR and CHARLIE X, can they? Would seem like too much of a swerve, plus it'd put whatever Qunito/Pine chemistry that is in there at risk (though I think it'd probably help with establishing any Spock / McCoy dynamic, assuming they are even willing to tackle that aspect with other actors.)
I don't think Abrams has any interest in that kind of Kirk. He wants Star Trek to be more like Star Wars--he said he found Trek "talky." Upon seeing the movie, I understood why he worried he might take Trek into Galaxy Quest territory. If he'd had episodes like "BoT" in mind, I really don't think that would have been a concern.
Suffice to say, I enjoyed the movie but I wished that Kirk was a bit more reflexive. I wanted there to be a scene or brief bit with Bones, Spock, Pike, or even Uhura where Kirk had to confront that perhaps he was wrong about his choices (e.g. the Kobayashi Maru Test) or even admit that he might be wrong.
The character Chris Pine plays is much closer to Gary Mitchell than Kirk at any time in the run of TOS. In fact--in an irony that was probably unconscious-- he's even
Marooned on Delta Vega.
