It is also completely unfair to put this movie down because it is an intro film. It is a reboot, that is what is needed.
I agree, and my overall reaction to the movie is positive (going back for my third viewing this weekend

). I thought as a reboot of the franchise and a re-introduction to the characters the movie worked very, very well.
My point regarding the origin story and connection to Spock Prime was more that these things do clutter up the story a bit and require a lot of attention so it is perhaps not too surprising that the film doesn't explore a central idea or theme to the fullest.
Also, I think there is every reason to believe the next movie will be stronger and more unified thematically. The connection to the "prime universe" was especially messy and contrived, so I'm looking forward to a movie that does not have to spend time on that.
