Here is another good review for Morgan Spurlock's 30 Days atheist in Christian home episode.

“One of the things that bothered Michael a great deal was his lack of understanding how people can live a valuable life and one that cares about the betterment of the world without having the Bible as a reference for living. It seemed to surprise them that non-religious people can raise responsible, respectful children and have positive, contributing lives,” said Frei, who found it much easier to bond with Tracy Shores.
