Wow! I really LOVED this movie; there's a huge story that isn't even hinted at in the trailers. Also, it's not really plot-driven for the first half; it's character-driven, which was fine with me. For those who're expecting another "Independance Day" or "Transformers" spectacle, I don't recommend it. But for those who are into interesting storylines and characters, it's a must. I give it a solid "A." Also, at the end when you feel frustrated by some of the characters' actions, just keep this in the back of your mind-- it's all gonna work out in the end.
The movie was mostly good, definitely a lot of eye candy. Two things bothered me, though. 1) why didn't the people of Vulcan and Earth just shoot down the drill once it dropped into their atmospheres? 2) it took too long for the bad guys to explain their motivation on why they were after Spock/the Vulcans/the Federation. Also, if time-travel loops make you crazy, prepare yourself for time-travel talk in this film... Otherwise, it was a decent movie with likeable characters.
