This actually isn't true. The whole reason he was in Starfleet is because he bought the argument of Christopher Pike, after mulling it over a bit.
Ah, forgot about that. It's the only other scene though where he listens to anyone though, and he only listens because Pike goads him into it by double-dog daring him into it (which comes off as childish, but given who Pike was talking to, is pretty smart.) Also, I hate that scene because it establishes him as some kind of sooper-genius, which is actually used in the next scene you mention, but it doesn't work that way that it was supposed to.
He later reveals on the bridge when he races in that not only has he read Chris Pike's dissertation about the Kelvin incident and remembered a key detail, he'd instantly put it together with an offhand comment Uhura had made the other night to her roomate while Pine was half-naked on the floor and made a snap conclusion.
Ah, but remember what happened
before and
after that scene. This entire sequence of dialog took place after Sulu's "Alzheimers moment" with the controls, which means that they're far behind the rest of the fleet, which was destroyed by the Narada.
If you recall, Kirk's "sooper genius" moment was to try to convince Pike to raise the shields...because apparently they weren't going to raise shields in response to a
entire planet being under attack by an unknown force (which
was mentioned in dialog prior to their departure.)
Perhaps Kirk's snap judgement was sort of impressive, but he used that point to beg for a course of action that only the dumbest motherfuckers wouldn't have already thought of in that situation. Besides, the Narada didn't immediately notice their arrival because they weren't looking for other ships, as they would have assumed that Starfleet sent the fleet as one unit. Sulu's Alzheimers moment actually did more to project the Enterirpise than Kirk's "flash of obvious" moment.
That's not clever characterization, that's
bullshit. Kirk only comes of as a genius because the rest of the crew is apparently retarded.
Spock, now, the whole stupid 'off my ship' notwithstanding - the writers really got Spock and what made him tick. They decided to shove him over the edge a lot (and give him 'rock'n'roll', which means his rather pointed rebuttal to the Vulcan Science Academy); but his being bullied on Vulcan and personal struggle to control his emotions are pretty important to how he ticks.
I'll admit, I liked the early Spock sequences before we see him getting into Starfleet. That was actually fairly well done.
Most importantly, though, these guys are alive. They've performed with great verve and winning, star-making charisma by both Pine and Quinto. Electric chemistry compared to the totally, deadweight, 'I'm just reading these lines for my paycheck' performances dialed in by Neeson and McGregor.
Pine just came of as an obnoxious fuck the entire time, most especially during the aneurysm-inducing Kobayashi sequence, where he made it so obvious that he rigged the damn thing that there was no point in having an investigation. Now, I'm not sure if that was specified in the script (which I'm guessing it was, given how fucking proud Orci and Kurtzman are of that scene,) but it didn't strike me as particularly memorable.
Quinto, however, is a good actor to start with (and a fellow Pennsylvanian), but like Pine, couldn't really shine to his full potential because of some very bad scenes, like his
instantaneous love affair with Uhura. I'm sorry, but one, very short scene in the Academy hangar does not a romance make. Again, part of this working hinged on some of the audience knowing that Spock and Uhura initially had a "thing" going on in early TOS, and part of it hinged on being out-of-the-blue to everyone else, though who else was going to get the girl, now that Kirk is an uncharismatic ass?
