I thought Kirk was a little over-the-top annoying, and early on I was worried this was going to be Top Gun in space. But they moved past that set-up pretty well. Spock was all kinds of awesome. And little Chekov was way adorable (he's in fact making me actually want to see T4 — maybe that guy as Kyle will counteract my anticipated dislike of Christian Bale as John Connor).
The theater was packed and everyone seemed to have a great time. We had three generations of people in our group and we all had a blast. Oh and at the end, the theater erupted into applause. Cool. I don't remember the last time that happened at a movie. So go see it if you haven't all ready. Star Trek is a rockin' good time.
