I thought the movie was pretty good. I never watched anything Star Trek before and most of my knowledge of the series comes from references in other media (that Futurama episode, etc). One thing I both liked and hated was how every character origin wasn't so much an origin, but the transition. You get a very brief look at the starting point, then it's done. Like, you see Kirk born, then you see him in that car sequence, then he's old and hitting on Uhura (sp?) in the bar. But wasn't he stopped by a cop for stealing that car? and what about his stepfather and mother? I guess it saves time to gloss over all that.
The cast was mostly good even if it just seemed to really focus on the Kirk-Spock relationship. McCoy (sp?) was awesome and I wished they had more of him there. The nuclear wessle guy was a bit annoying. Simon Pegg was alright. Sulu was cool for the few moments he was on screen. If there is another movie I'd like more focus on the crew and not just those two. Nero was pretty cool too, even if his motive for being a villain was really thin. And the comedy aspects felt really out of place, especially when Kirk had fat hands minutes before doing that huge action scene.
I did like the time travel going on and how it was explained. Old Spock was cool when he was dealing with Kirk, but when dealing with young Spock it was pretty lame. Though it was funny how they basically said "lol, there will be no paradox" in that scene. Best part of the time travel was how they showed how the 125-year future technology was a lot more advanced than what everyone else was using. Nero's ship was a mining vessel and it was dominating the top of the line combat ships. Spock's ship has the ability to create black holes and destroy that drill ray in a few shots. The one part I didn't like was how old Spock told Simon Pegg that equation. It would have been better of Pegg thought it up on the spot when he realized it was possible, not just given it.
And Kirk getting the shit kicked out of him throughout the movie was awesome. 70% of the movie is Kirk getting fucked up or having visible damage from when he was fucked up.
So yeah, it was pretty good.
