Star Trek's a good summer sci-fi action romp type picture, I'm a little split over how good a STAR TREK movie it is, I may be too deeply vested in Next Generation, which I started watching around 1989-90ish, and it's of course hard for a two-hour movie to measure up to all the high-points that TNG scored over the course of seven years...

Nevertheless, it's a great movie, not too much technobabble, casting was great with excellent portrayals from most of the actors. The badguy was perhaps the movie's weak spot, though it seems movie critics didn't hit it for over 9000... :P The handful of reviews I've seen have all given the movie 3/5 or better, which is Very Good for a Trek movie.

I myself would have preferred a more sinister badguy with more screen time assigned to him. He feels rather undeveloped, and his reasons and motives don't become clear until quite late in the movie, unlike say, Khan, whom is much more colorful, and you get a good grip of as a character right from the very beginning even if you never watched the original Star Trek episode where he first appear.
