Hmm, honestly I didn't notice a problem with T3's score. Elfman is an interesting choice, should be interesting to see what he does with it.
It was ok, but often it sounded like any old action film score. Like T3 as a whole, the score lacked any serious sort of *** at humanity and where it was going. Ya, Terminators a sci-fi action series, but one of the cool things about Cameron's work was that he had an underlying message about humanity and the future, T3 seemed to set that aside and just have robots kicking each other's ass.
