I like the fact the movie is both a reboot (like Batman Begins and Casino Royale) and an offshoot.  The fact that the movie creates an entirely different timeline for this batch of Trek movies opens up the possibilities for so many reinaginings of prior Star Trek stories.  Like the way current comic book movies gets inspiration from a bunch of different comics, this new Trek can take some of the best ideas in the show and put them together into one kick-ass movie.  Already people are talking about how cool it would be to bring back Kahn.

More than anything, I really appreciated how the movies had acutal production values.  I loved TNG on TV, but when it jumped to the big-screen, they always felt/looked like a made for TV movie rather than something made for the movies.  Oddly enough, the original cast Trek movies seemed to have better production values than the TNG ones.  

I thought the action was well done (perhaps a bit too much shakey-cam) and the acting was top-notch.  I thought everyone was well cast as their respective characters.  And for anyone who says that Kirk and Spoke were underdeveloped...have you seen the other movies?  Sulu, Uhura, Scotty, and Chekhov are total window dressing in the old movies with NOTHING to do.   The pacing was fast, and while some of the story really didn't make sense (did Kirk ever graduate from the Academy?  How does a cadet go from school to 1st officer just like that?  Is the entire crew of the Enterprise new grads?  Did Nero just sit around in space for 25 years waiting for Spock?  Did Nero really have a plan to destroy planets or did he come up with that after he captured Spock?) it was fun and interesting.

The biggest compliment I can give to this movie is that it managed to make Star Trek just as enjoyable as Star Wars (espically the prequel ones).  It finally managed to stop all the talking and actually do some doing (which is ironic becuase the Star War prequels took the doing the the original trilogy and did a whole bunch of talking).
