I loved the show, especially showing and contrasting the differences in the views, that is what America is all about. The right of people to openly disagree. The liberal son (Dan?) was abrasive...but it's probably has a lot to do with that he's a teenager, and I saw a short clip of his mother talking to him about it after they reunited. Hopefully as he grows older he becomes more empathetic and understanding of other people's views and he learns that listening is part of communication.
I was not that impressed with the conservative mother. I found her equally abrasive. Why would anyone think a military style would be an appropriate way to also raise a family, unless straight shoes and well made beds were the most important aspect of a family life? I'm glad she saw some need to change in the end, but taking a step back, it seems her family was the most screwed up. I thought it was funny that she said that the husband needed to be the head of the household, when in reality it was always her. I would like to know if she thinks Jesus would have enlisted in the Iraq war?
