A straightforward action movie that satisfies like a cold drink on a hot day. A good, but not great film. Probably too ambitious in filling in the back-story, plus developing a plot, to really develop the characters. So the resources of the movie were stretched a little thin. But what can you do in two hours, given the 40+ year history of the Star Trek franchise? Probably the best film that could have been made given all the constraints. Really good casting and special effects.
