Brilliantly shot, great soundtrack but terrible script. Such a cliched plot unfortunately that can be found in countless B movies. Such a shame as Gina Carano is not only hot but she has a great screen presence too even if her acting is not the best. Friends in high places for Soderbergh gave this movie much more attention than it's plot deserves.
Despite a general mauling by the critics, I was still intrigued enough to watch this as the director Chris Gorak made the excellent low budget post apocalyptic thriller Right At Your Door and this very nearly makes it onto the cult classic radar if it was free from studio interference that plainly wanted the film to appeal to a younger audience. It is an unusual alien invaders film and has some really original set pieces but the first 10 minutes is awful and the film treads an uneasy line between crowd pleasing plot lines and indie cred. Much better than it should be really and I was pleasantly surprised as I wasn't expecting anything from this movie.
