Star Trek has been my mother's milk, growing up. I was ready to be disappointed by this movie... and wasn't. I was thrilled. It's still "Trek," if faster and not as deep.
Still, just like Chekov's w's this movie suffers from hyperovercorrection. Old Trek movies have been (accurately) accused of slow pacing; the new Trek is much more frenetic (partly because of the presence of two bildungsromans) but the scene changes are so notably different that it's all memorable. The later series and movies had a tendency to treknobabble their way through problems; in this one, such is limited to "red matter," which is red and vaguely matterish but not described at all beyond the fact that it does Bad Stuff..
