I've finally seen it a couple of weeks ago, and I liked it. Off course, some things didn't match with the star trek canon and all, but the movie was great. It had some great special effects, a lot of action and humour, and like the new batman and james bond movies, it was more raw, and a little bit more realistic looking, for instance, the shuttles had rust on them, the interior of the ships are somewhat more of what you would expect from a spaceship.
Vulcans always felt superior above humans in the series, now they are even complete racists. Young Kirks gets a severe beating in a bar, and uhura has a roommate who doesn't do much else than dating boys. These are things you never saw in trek, but make sense. Star trek always had a message of tolerance, but what they portrayed in the movie compares a lot more to human nature.
I don't like the new romulan look however. They look like real villains now, instead of a race with it's own civilisation. They really shouldn't have done that.
