If you're a Trek fan (and you know if you are) then this is a must see film, but while JJ Abrams does a good job with most of the action sequences, the writing and editing of this movie is haphazard, and there are moments when you'll turn away from the screen because of all the flashy .25 second editing of cuts.
Literally, I turned away from the screen several times. This tendency that directors have (market-tested to be sure) to linger on a shot no longer than .86 seconds is really tiring on the eyes, and on the brain.
This film seems to be JJ Abrams ode to Michael Bay. He seems to be saying: "See, I could have done Transformers too!"
