As with all reboots, or at least all those that I've seen, there is a lot more action in the new version. Sometimes it takes over and dampens the experience for veterans of the series (see James Bond). In this movie there was plenty of action, most justified and worthy. However, Spock fist fighting with Khan for several minutes seemed out of character for Spock. And I admit I still have a hard time accepting Chris Pine as Kirk. Too boyish looking, though he is a fine actor.
There was plenty of action, tension, excitement and humor in this movie to push my concerns aside, and so I really did enjoy this one. Production values are awesome throughout and J.J. does not disappoint. Highly recommended.
Whither next, Star Trek?
