I gave it a C grade.
The over all film was okay, but it had a lot of problems. One of my two biggest problems was the death scene. It just didn't work and took me out of the film. The other one being Spock this time around. I just don't think the acting was what it was in the last film, and in the last film Zachary's Spock was perfect!
There were things that I liked, like teamwork, Kirk and Uhura's transporter friendship scene, McCoy's "Are you out of your cornfed mind!" lol, Sulu having a chance at the captain's chair for a minute, and the small attempt at S/U, also liked that Kirk listened to Scotty when he said not to use the torpedoes, Pike, Nimoy's cameo, Cumberbatch was nice, and Chris Pine really did a good job this time emoting (he did a nice job last time, but this time was even better).
That's about all I've got right now.
