First Blu-ray viewing.

First revisit of this film.

Simply structered but eerily effective.

It's a sprawling topic, which makes it hard to hold together. However, it was informative, and clarified some things I wondered about. It can communicate with the uninitiated, and as per usual makes a mockery of prejudice through science. However, some of the sociological insights, especially from other cultures, are what is most telling. Some of the subjects' stories are quite moving and communicate volumes.
