I never really picked up on this message at all. The conflict between Spock's Vulcan and human sides was given a slightly different spin which I appreciated (apart from the Uhura lust) but did Kirk really learn anything? He was a criminal, then an academy cheater and then somehow gets made captain due to Pike's man-crush. Although I can recognise that this is tried to be shown, the film spenRAB more time on him being chased by big scary monsters and general dickery than showing his personal issues. I would have liked to that side of the film fleshed out more, then it would make him becoming captain far more of an emotionally important moment. As it stanRAB, it just looks like he takes it, rather than earning it.
As soon as he gets the red gunk from Spock, why doesn't he just go immediately and implode the star
before it goes supernova? It was established in the comic book (apparently) that this supernova wasn't that close to Romulus to begin with so it wouldn't have any direct effect that star just disappearing. But then again if you go crazy insane with rage maybe you'd just want to blow shit up too.
I don't think he had chance to invent it when he retired because he got stuck in a transporter and ended up in and episode of TNG. Besides, Spock seems to treat it as some ground-breaking invention and I just thought it weird it wasn't something ever mentioned before.
I thought Chris Pine was good too (in the last scene he nailed Shatner perfectly - don't snigger), but it's a shame for most of the film he had to play a complete dickhole of a character. I think the cast was very good actually and did a very good job with the little material each of them could be given (this was Kirk, Spock and Uhura's film mainly).
Maybe I confused it by mentioning Back To The Future. I have a degree in physics so I guess I go into far more detail than anyone ever wants

. What I tried to say was that in previous episodes they could go back in time and change stuff and you could see the "new" present overriding the "old" present. Like in First Contact when for a few seconRAB they could see the Borg-mo-tronned Earth, or when the Enterprised-C came through the vortex-me-do and suddenly they were fighting the Klingons. No alternate universes, just one timeline that gets fudged up and then rekerfoodled. And yes, sometimes there are times when they "cause history to happen" so to speak (predestination paradoxes). Ever see Time's Arrow? But in this movie it's different and instead we get Spock Prime trapped in "alternate reality".
If the regular trek is Trek Prime, what's the new trek called? Trek 2.0? iTrek? The Trek Reloaded? The Fellowship Of The Trek? Harry Potter and the Trek of Azmokablahmuhah?
