Anyone that likes your outerspace science fiction should love this. The actors/actresses are all top notch. You get the feeling of loving the good guys (i.e Josh-Aaron Elkhart, Braz, Hillary Swank, and start out hating the jerks like Zimsky, General Percell, But in the end you love them all. Such as Serge's quote, " you're trying the impossible. I came down here to save my wife and 2 children, and 6 billion people are to much; I just hope that I am brave enough and smart enough to save 3. You are trying to save the world, and it's too much" that's probably not verbatim, but it's close enough. The all star cast makes this movie great. They ARE the movie and without the cast you couldn't have the movie that there is. It's a great movie that integrates all of the true science that we have to date.......Definitely go see it/rent it.
