In my opinion Goldsmith's score for Star Trek: Insurrection his is weakest, and most uniteresting, score for a Star Trek film to date. The biggest reason for this is probably the main theme. When the other Star Trek scores have been blessed with powerful themes, the main theme for Insurrection is a very sweet one played on harp. It's very beautiful and all, but it's not what I had expected to hear in a Star Trek score. I know that this, the ninth Star Trek film, is supposed to be more romantic than its precursors - I haven't seen it, so I can't tell - but... well I expected to get a memorable sweeping, or lush main theme, like the one for Star Trek: First Contact.
Then there's another theme related problem. The action music lacks a good theme, too. The action music is very, very good, but I think that a memorable action theme would have made it outstanding. The action music, and the music in general (except for the main theme), is very brassy, as one could expect it to be, and is also very percussive and heavy on synths. Very much like Goldsmith's earlier contributions to the Star Trek films. And maybe this is the real problem. I think it would be a wice choise to let another composer score the next Star Trek adventure (if it will ever be made, that is)? It's always (almost anyway) good to get some fresh ideas, and it would be interesting to hear what a composer like... Joel McNeely for instance, could come up with.
Oh, and in case someone wonders Goldsmith makes use of Courage's classic Star Trek theme in the first and last cues. No Star Trek score would be complete without this theme. Even if it's beginning to get a little worn-out, in my opinion.
