I quite like "Nemesis". It has its flaws, but so do all the Trek films. I didn't mind the dune buggy scene - it was a fun scene that some fans get way too uppity about. Some of the deleted scenes also add a lot to the movie.
Having said all that, the bits I wasn't too keen on:
* The need for B4... well, there wasn't really a need.
* The wedding scene. Glad it was there, but the TNG crew are at their most cringe-worthy.
