Yeah, that was cute.
Pine has a little Shatner moment on the way into Pike's office early in the movie; I LOLed.
I don't miss the original cast playing these characters, not one bit. They had a very good, very long run - decades, for goodness sake - and Kirk, Spock, McCoy and crew are excellently served as characters by the new cast.
Oh, and they appear to have added a new Enterprise crew member to the core cast: Carol Marcus. Uhura's skills and character are pivotal to this movie. So whoever it is who keeps harping on the lack of strong female roles in TOS can stop, now.
