This movie had a cool concept and it was well acted however logistically it fell apart. I for one was able to tell what all of the characters had in common, apparently the only survivors of a world-wide virus catastrophe are Americans (as the movie doesn't specifically say but leads you to believe) with Italian accents. If you want to have a movie portray Americans then shoot it with Americans or at least actors that can speak with an American accent. This is not to say it wasn't well acted because it was, this sticking point just stuck out to me like a sore thumb. Other than that it has some large ideas to grasp which maybe could have been developed more but I like the fact they tried to tackle it and with a nice little twist at the end. See this movie with half your brain tied behind your back but keep your head in the game and you might enjoy it.
