Most of it felt like Star Trek, and an honourable mention has to go to the very last scene, when Kirk strides onto the Bridge in his captain's uniform and calls out, "Bones!" The way Chris Pine channelled William Shatner was spooky.
Hmmm...I didn't get much of a channeling Shatner vibe from Pine. I actually felt like he was going out of his way to create his own representation of Kirk and to avoid Shatner's mannerisms and speaking style. Pine has said in interviews that he was told to do it his own way.
