This is the movie that all summer franchise movies wish they could be. Everything about it is great, from the casting to the special effects to the story. Lots of Easter Eggs for long time Trekkies like me (and yeah, I don't hold with that "Trekker" nonsense, I am and always have been a Trekkie) and more than enough to hold the interest of even those of you saying, "Star what now??"
Benedict Cumberbatch is a revelation. This is the guy who held his own with Gary Oldman in the recent Tinker, Tailor, Soldier, Spy. He is riveting as John Harrison. Sherlock fans better hope he likes the role enough to stick around for a while, because television is too small a medium for Cumberbatch's talent. His are the most nuanced performances I've seen since, well, Gary Oldman's.
The rest of the cast, all returning from 2009's Star Trek reboot, do a bang-up job as well. The scenes between Chris Pine's Kirk and Zachary Quinto's Spock are priceless.
So go. Go now. You won't be sorry.
