Fresh and thought provoking, the film is a showcase of the mindset differences between the sheltered younger generation, and the roughshod older generation, in the setting of an America that has been turned upside down by an unknown event. Many disliked this film as it was missing a proper closure and explanation, but I feel the movie very accurately portrays the reality that you cannot expect to always find an answer in life - and in the face of the apocalypse, why it had happened has no significance at all to the people affected, the only thing that matters is how one decides to live. I wont have wished for the film to be any other way, and wish that more people can view this as the mature, thoughtful piece that it is.
