Not heavy sci-fi, more of a man vs nature story. 3D was very good as was the story. Don't worry about the running time, it goes quickly. Although not a "great" movie, it is very good. Go see it, you won't be disappointed.
Non stop action, good story, good acting and just maybe the best Star Trek movie ever. It is definitely up there with "Khan", but sentimentality won't let me put the new one on top of that one. If you've never seen a Trek movie or watched the TV shows, don't worry. You won't get some of the small things but you will enjoy the movie. Very happy with JJ Abrams version. Can't wait until the next one.
