I think Zachary Quinto will do a great job of playing spock - he's so deliciously evil in Heroes!
I liked QofS - it definitely wasn't as dark as Casino Royale, but it's still dark in comparison to earlier Bond films. They really give Daniel Craig a workout with some of the stunts though - it's almost too much to believe - seems like he's superhuman.
I was disappointed that there were no gadgets - that's usually the best part. They did have a fancy computer system, but that was really only one scene.
