I had to go with OK, because while I've warmed up to the idea of the film and am geniunely looking forward to seeing the performances of Pegg and Urban, I'm VERY MUCH put off by a certain event in the movie (which I can't and won't discuss here, go to the spoiler thread and see my comments if you really want to know).
So I'm kind of middle of the road about it right now. I think I'll like it, but I'm not happy about one pretty major event and to me that event is very significant to the Trek universe.
