Giacchino's score, which has grown on me in repeat viewings
I have to say that the score has grown on me as well. In the theatre, I thought that the score was the weakest element, but it seems to have staying power.
The plot holes are more obvious on repeated viewings but fortunately the film's just so much gosh darn fun that I can still enjoy it.
I feel that the plot holes seal up quite nicely with repeated viewings. I particular, the problem of locking onto the falling Kirk and Sulu, when orbital speeds are generally faster; there was a black hole being created, so there was extreme gravitational distortion (Chekhov had already calculated the effect of the black hole in determining the speed in which Vulcan would be destroyed and revised those calculations to do the the transporter lock)
I'm still not a big fan of the opening with the Kelvin. George Kirk's sacrifice strikes me as melodramatic rather than genuine emotion, although the score goes a long way almost selling the scene.
I disagree. I think Jennifer Morrison sold the scene for me.
Spock Prime's explanation of what happened in the 24th century still is a muddled mess. It's easily the weakest plot point of the movie, although it's far from the weakest scene, since Nimoy so effortlessly sells it.
I think in that bit, Nimoy may be filtering a little of the history. This is a highly compressed, trippy flashback, that conveys as much emotion as it does fact. I believe Spock censored much for Kirk's benefit possibly making himself appear less culpable for the future destruction of Romulus and the Past/Present destruction of Vulcan.
