After seeing the movie and listening to the soundtrack again... I still found it overall very bland. The new theme I like, but the action music just runs together. I've also listened to the Revenge of the Sith soundtrack and I find that Williams does a much better job of writing action music that is interesting to listen to. Now some of that isn't a fair comparison as Williams does have 20+years of themes to work with, but I tried listening to the underlying (non-thematic) music and I still thought it was much better. The Star Trek Sound Track really only 'pops' when Giacchino adds in his fun percussion work (like the epic timpanis in a few spots), but overall it doesn't do much to evoke emotion from me. It is sort of just there. I think that it could have stood to have a rewrite done of a few scenes and added in a theme or two.
A Spock/Vulcan theme would have been great because it could have been explored in many different ways throughout the film as Spock goes through many different character states and could be used to highlight the pain he feels in certain scenes and also highlight the differences between young Spock and Spock Prime.
