I saw it a few days ago and it was AWESOME. And watching all the original series movies before totally paid off. I know there were probably a billion references, but the two I enjoyed the most were 1. the entire Kobiashi Maru simulation thing (with Chris Pine doing hilarious Shatner line readings) and 2. the parallel to the part in Star Trek 4 where Scotty "helps" the engineering guy invent see-through aluminum. "How do we know he didn't invent the stuff?" Oh, and of course the obligatory red-shirt. (Speaking of which, I want this shirt.)
But even if you know nothing about Star Trek, it's still a fantastic movie. I want to see this movie again in IMAX and I want who ever makes them to make a whole bunch more.
