I like the movie a lot. They were able to rewrite the history of the original cast and not shoot the established canon(sp?) in the ass. I found it pretty inventive as it gives them more freedom with the sequel.
The only thing I had a problem with is that they stranded older Spock in the alternate universe. Not a big problem other than it messes with Trek Lit. And they destroyed Vulcan!!! Holy crap!!! I didn't think they would actually go through with it so that was a nice surprise.
Overall great movie in my opinion.
