Labiak is right. It follows a family and there different reactions to a possible future. It is very nuanced. I would not agree with Lessismore; I certainly didn't see it as "devoid of optimism and hope". Much of any optimism came from the family dynamics. Each family member held very different views but they managed to keep their family ties. We saw heroism, cowardice, self-sacrifice and self serving against a background of progress and regression. I must admit I felt it could have been longer - to play out the passage of time in more depth. It was a dystopian "future", but only some members of the family allowed it to dehumanise them. Just as in an country under occupation some rose above the new order, some sank beneath it, and some just struggled to survive.
