Let me start by saying that Mr. Spielberg better watch his back because J.J. Abrams has kicked things up a notch with this film. Abrams, mostly known for creating the TV show Lost and his work on Cloverfield, has etched his name in the books as a true action film maker. The film is absolutely stunning from beginning to end. The SFX are incredible and definitely not lacking. The cinematography goes right along with that. There are some camera shots that are unique and brilliant, and certainly memorable.
The music is what it should have been for a Star Trek film: loud with a very large brass section. Throw in a bit of the Beastie Boys and you have yourself a good sound track.
I felt the film dragged on a bit during the middle and the story took an interesting turn in the middle. I wasn't a huge fan of the direction it went, but I've seen worse "twists" (ahem...Hancock). Bring your thinking cap, because there's a lot of physics stuff being thrown around and it gets to be a bit much after a while.
One of the downfalls to this show, at least for me, would have to be Zachary Quinto. I am a fan of the show Heroes, so he will always be Sylar to me and I didn't really see any deviation from that character. He seemed to be trying too hard to act like Leonard Nemoy, and it didn't work. Thats just my though though. I've never really been a big Spock fan anyway, so personal opinion there. All of the other actors did great. Karl Urban is a dead ringer as Bones and does an amazing job. Simon Pegg was awesome as Scotty, but very under used. Zoe Saldana is H-O-T! Although I am a fan of Anton Yelchin in his other films, he seemed a bit over done here: the accent was bad and he seemed a bit childish I guess. I was not so thrilled about Chris Pine being cast as Capt. Kirk, but he pulls it off pretty well
As a whole, the show was great. It captures your attention right off the bat and, for the most part, holds on to it. I'd tell you to sit back and enjoy the ride, the scenery and the very well written script!
