It was simply amazing! I loved this one probably a bit more than the last one. I'm going to see it in 35mm this weekend, but a couple nights ago I saw it in IMAX 3D and it was mind-blowing!
Beyond the visuals, I have to echo the praise for Chris Pine. He wasn't Pine as Kirk or Pine as Shatner as Kirk. He was playing James Kirk, plain and simple. The beginning sequence on Nibiru into the credits, for one, was simply outstanding and made me feel like I was back in 1982, discovering TOS on TV and feeling the excitement of meeting a new group of friends.
I actually found myself tearing up a bit after the warp core scene.
This was not only a great Star Trek movie, but a great movie, period. I saw Iron Man 3 a couple weeks ago, and as a movie itself, this blows STID blows it away.
