As far as I'm concerned the film is a tour de force of prioritized budgeting. He got a brand new model (Reliant) and innovative early CGI and first-rate battle scenes courtesy of ILM. The only FX shot off the top of my head that didn't work that well was the underground matte shot. Even though many TMP assets were recycled, they still came across as different. The bridge was redressed, the new uniforms, the conversion of the Klingon bridge into the Regula I control room. Just the right amount of money was spent doing just what was necessary to give the Trek universe that soft-reboot into a nautical feel.
