Erg, some of that sounds weird.
Kirk acting like James Dean? Too obvious.
Voice over with Daddy Kirk telling his son to find! his DESTINY! in the stars! Cliched.
McCoy ranting about phasers & death? I know he can be an old granny, but that doesn't sound like his usual way of expressing himself.
But baby Spock sounds cuuuuute.
Awwww! And who doesn't want to see Spock try to kill Kirk? As many times as possible.
In fact, if they want to reboot the whole "under a bridge" scene with something that will piss of fans even more
