This is one great movie.
J. J. Abrams has gotten it. He's captured what the original show and movies had and has brought it to life with a new cast. His 2009 Star Trek was pretty good, but this one is better.
I read a couple of reviews of the movie and I have to say that the reviewers did not get it. At this point, Star Trek has a lot of history. Abrams has mined that history well to present this alternate universe Star Trek that remains true to the original. If you know a lot of that history, then the movie has a lot of depth that you'll appreciate. If you don't, the story stands on its on.
I'm not going to divulge the plot here just in case you've not been following all of the publicity. You can look at the IMDB page if you want the ultimate spoiler right on the front page if you want. I'll just say that my wife is a fan but has not been following closely so the main plot came as a surprise to her.
The one review I read thought that this was the funniest Star Trek. I wouldn't go that far but I there are a lot of good lines, delivered with style and a sense of awareness. McCoy gets to say "Dammit, I'm a doctor not a weapons technician". and "Are you out of your corn-fed mind"? Kirk tells McCoy "Enough with the metaphors"!
I can hardly wait to see the movie again. I only have to wait until Thursday. My daughter and I are going to see it again, but this time in 3-D IMAX.
