I'm watching Nemesis right now, to finally conclude my Trek movie marathon and I honestly think it's now my least favorite movie. Before, it was The Motion Picture but Nemesis is truly a piece of garbage.
Does anyone on this board really love this movie? No judgments if you do, I'm just curious to see if there is something I'm missing.
You can judge whatever you want.

I used to rank it 5th but now its 4th. Why do I like it? Its the biggest scale ST movie since STTMP. It has good production design(the best of the ST movies except maybe STTMP), set-piece FX and action sequences like a modern SF adventure movie. Firmly establishing it as the first modern ST movie.
While you can quibble with some plot choices, it has the fewest inconsistencies of any of the ST movies save perhaps STII. It has a central plot dealing with Picard, and involves him both on a personal level as well as professional, not all the STNG TV stories did that. A vulnerable Picard from the movies (STFC) makes for good viewing. Data, my second favorite STNG character also has a good bit to do in the movie and he has quite a spectacular farewell at the end. I also enjoy the presence of the Romulans and their new ships, though they I wish they hadn't been under the heel of Shinzon. Tom Hardy is underrated in this role, which is quite dark.
Its also a myth the viewers didn't like the movie. The movie rates well on the major rating sites, and had a high cinemascore by viewers. It made close to $120 million from ALL sources (not just BO, and not counting marketing) and its DVDs sold well over 2 million copies, the highest for a first run ST movie until the monumental ST09. I've had great success introducing the movie to the uninitiated. Everyone has liked it, certainly more than Insurrection and several of the original crew movies.
By no means is it perfect. I wish they hadn't used B4, and there are a few slow moments towards the middle of the movie. I think it just came at a time when there were a lot of negative feelings toward ST in general and that kept the box office down for fans on the fence. Its so much better than STV, its almost like comparing ST09 to Plan 9 From Outer Space.
