I saw it twice and will probably see a third time. Loved all of the characters and the references to the TV show. I like when Bones first encounters Spock. "I don't know who he is... but I like him!!"
I could overlook the implausibility of this or that. Seriously.... we're debating how physics doesn't support parachuting from outer space but it makes sense to be beamed everywhere?
As far as the inconsistencies with The Enterprise already being in service when Kirk takes command ( the TV series), remember this is now an alternate reality because of the time travel so anything is plausible.
The scene on Delta Vega with the monster/creature was kind of throw away, for me. It did make me chuckle a bit, however, because it was J. J. Abrams' wink/nod homage to his series "Lost".
Saw it at IMAX also, and when young boy Kirk almost drove the Corvette over the canyon, I seriously thought I was falling out of my seat and over the canyon wall. Loved that scene.
