I already loved Karl Urban, but this is simply amazing.
For the longest time I felt that it was too slow, but with age I've come to a great appreciation of it. I really love it. It's still, you know, the essence of exploring the unknown. There's great character dynamics, with Kirk being a little rusty, being out of the chair, feeling threatened by Decker, and McCoy really calling Kirk on his insecurity. You know, Spock returning from Vulcan not having achieved the Kolinahr and coming back to his calling and his friends, and also having an agenda that's outside of the mission, his own personal agenda. I mean, there was a lot of interesting stuff in there. And then V'ger itself, the concept of something, an Earth probe, that was sent out and has become self-aware. I just think it was a really fantastic Star Trek story.
