I have two beefs with the PT music. The first is the lack of tight system of leitmotif — yes, there is an "Anakin's Theme" and "Qui-Gon's Theme" and all, but apart from "Across the Stars" they're not used the way his leitmotifs are used in the OT.
The other is the distinct lack of the main fanfare outside of the opening crawl. It's used in maybe one action scene in TPM and at the very end of ROTS.
