Documentary Review: The God Who Wasn't There (2005)

Since it's Christmas, we're focusing on more (mas) Christ related documentaries, this one called The God Who Wasn't There (2005) came out ~2 years before Zeitgeist (2007). Many of the claims made in Zeitgeist are outlined here in more detail, with a bit more angst as well. The bias is strong in this one, but are any of the claims valid despite that?
