Very enjoyable. Definitely not PC in any way-- as the reviewer who found the baby scenes inappropriate points out. I thought it was going to be a silly "frat boy" in Vegas type flick, but it had more substance than that. The plot did manage to drive the movie for me. I wanted to know what happens almost as much as i wanted to laugh along the way. It certainly had no shortage of silly frat boy humor, but it had plenty of other laughs to make it more than just that type of flick.
This movie entertained from the beginning to the very end-- from giggles at at some lines, to near uncontrollable laughter at others with plenty in between.
A great flick! The youthful version of the main characters really hit the spot. Their personalties tie in seamlessly with "your grandfather's Star Trek." And that, in large part, makes the move truly great. Yes, the plotlines are good, the action outstanding, the acting very good, and they even do a decent job of screwing with the time contiuum-- always a very risky plot device. All of these things contribute to this being a very enjoyable flick. But the portayals of Spock, Kirk, McCoy, and Scotty -- and the development of Aruora (sp?), Sulu, Checkoff, more than they ever had during the show-- with their distinct personality traits not left to nuance, but focused on and even exaggerated, makes this film a must-see pleasure.
