The good: The reinvention of the Star Trek universe. The effects and style of shots are very modern, with an upgrade on the teleporting fx and the way the ships "burst" into warp or the new way of destroying a planet. The actors filled their roles perfectly adn the story was very interesting.
The bad: Not much here, but they did overdo the dialogue references to the original series--especially with McCoy. The villian could have been explored a little more, perhaps if the filmmakers made the audience "feel" the agony of his great loss to sort of empathize and understand his madness.
