i loved it. i'm pretty sure there were a lot of jokes i didn't get, not being a trekkie, but there were a lot of jokes i did get, and they were good.
plot is absolutely secondary in this movie. it's just a funny, fun, exciting way to spend 2 hours. casting was great, and you walk out of there waiting for them to make a second one. so much of this was the "reboot", introducing a new generation to the characters and the idea of star trek, that you know they are going somewhere with it.
one complaint- not enough simon pegg. i usually say simon pegg isn't good unless he's got nick frost to back him up, in something written by edgar wright, but this was the perfect role.
