I wanted so much to like this movie. Maybe I wanted it too much. I have to spoil a major plot element to tell you why I didn't like it unfortunately.
Seriously, don't read anymore if you don't want to know stuff. There actually are a few surprises in this film.
The casting was good. The sets and costumes were good. The special effects were... different; not especially better so I don't know why they needed an update for things like beaming, but it was different.
The dialogue was ok, better in the first third of the movie than in the remainder. They kept trying to cram all the familiar characters' catch-phrases in, and it was... indulgent. I suppose they had to do it, I guess I wish I didn't feel so patronized by it.
Oh, and they managed to do product-placement. In a Star Trek movie. Seriously.
At least it wasn't as bad as Phantom Menace. Instead of Jar Jar we got... the old man. It was almost as bad as watching Dick Clark at New Years. Things were going fine until he showed up. Well, not fine exactly, there were massive plot holes explained away by the effects of black holes on space-time, but that's kinda par for the course with Trek I guess.
The villain was lame. Khan was a great villain, hence Wrath of Khan is widely regarded as the best Trek movie. Christopher Lloyd played an amazing Klingon captain. This villain's role was counter to the old saying that there are no small parts only small actors. There was just nothing to him, the flimsiest of pretexts for his murderous ways.
I would give the movie, as viewed, 1 out of 5 stars. If you cut out every scene with the old man, the movie wouldn't make much less sense and it would be way more fun to watch. I'd give it probably 2.5 out of 5 in that case.
Oh, and Scottie's little alien buddy, wth?
