I thought this was a great movie. While a die hard Trekker may have some problems with some things, I do not.
This is by far my favorite of all the Trek movies. I think it is great that the movie rewrites Trek history as we know, and they did a great job with Spock explaining the way it used to be.
They did stay true to a lot of the original stuff. It was great seeing Kirk beat the Kobayashi Maru. As we all know, he is the only one to ever beat it. :-)
All in all...obviously, I thought this was a great movie, cant wait for the sequel!
