My brother and I just finished watching the Star Trek movie - and I have to say, I was impressed. I can't remember the last time I saw a movie that had such history to live up to, that wasn't a flop.
I thought the movie found a good balance between action and giving us casual trekkies the one liners we came to hear. Sure, the story was a bit far fetched, but still, I found it was fun to watch. David brought up a good point - they didn't let the technology (yes, I'm looking at you Star Wars and the Matrix) steal the show. Sure, the effects were impressive, but they didn't eclipse the story or actors.
To me, a good Star Trek movie is all about parallel problem solving. What impossible mess do they get themselves into, and how do they figure it all out. And the movie delivered in this department.
I give it a 9.5/10.0 (sorry, it didn't feel like the Perfect Film) for being such a fun movie to watch, and for giving me a nice Star Trek fix. Go, see it.
