This film tells us the beginning of a new Star Trek. A Star Trek that recaptures the sense of fun and adventure the audience in the 60s and 70s (and I as a kid of seven in '87) has felt when they saw Trek for the first time.
What exactly does recapture? The uniforms? Ok. The lines the characters speak? Maybe. Saving Earth on a constant basis? Not really.
I don't know about you, but I don't remember any episodes from the original series that involved the 23rd century Earth in danger of a genocidal mad man. In fact, I don't think any of the original Star Trek episodes involved the 23rd century Earth in it's entire run. Sure, they went to Earth's past, but that was the limit of Earth's involvement. Everything that involved fun and adventure was mostly about what was out there, and not back here. But oh, no. This film doesn't want to go out there. It
LOVES Earth. It loves Earth so much that anything not Earth, no matter how big, unique or important it is to Star Trek is considered expendable. Why? Because nobody gives a crap about anything but that over emphasized blue ball.
Now you're probably saying "But Jeyl you flat headed ignoramus, Star Trek is a 'human adventure'." to which I would agree with, but again, let me emphasize that point. It's a human adventure that's about going out there. Where in this film did any character express any interest in wanting to that? Did Kirk look up at the stars and think to himself "I want go and see what's out there"? No. He looked at the Earth bound Enterprise and thought "I'm going to make that mine".
