I watched the first part last night on The Nature of Things with David Suzuki. It was pretty good, although the emphasis on how Darwin was afraid to discuss his ideas got a bit tedious.
I'm also skeptical about the film's claim that evolution caused Darwin to abandon religion. It's worth remembering that his father (Robert) and his grandfather (Erasmus) were well-known skeptics about religion and Darwin's brother, Erasmus, was not religious. Darwin hung out with a lot of people who were questioning religion even though they knew nothing about evolution.
