The first 2 Star Trek movies are really good, it's rare I can be arsed watching any of the rest though. I'd rather just watch a random episode.
Well, I personally don't like The Motion Picture, but I'd say I actuall like more of the movies than I dislike. I can even watch and enjoy Generations and Nemesis, although I acknowledge that they are far from good movies. Insurrection, ST V and The Motion Picture, though, I just really dislike.
