This is the first star trek movie i've seen that I wouldn't mind having a sequel to with the entire cast they picked. Honestly everyone fit their roles perfectly. The movie was exciting, it brought you into the story, and meshed well into the Star Trek universe without trying to give everything a hollywood shine. The character they cast to play Bones was magnificent and even though I was worried about Simon Pegg he did a great job.
Do not hesitate, star trek fan or not you will enjoy this movie, I took three non-star trek fans and now they can't wait to see a sequel, JJ really outdid himself this time.
