Our second of the pair of Terry Zwigoff documentaries is one that initially no one wanted to touch, despite the success of Louie Bluie. Was it just that all that good will had evaporated over the course of a decade? Or was it that this time around Zwigoff turned his camera on his friends: gonzo cartoonist R. Crumb and Crumb's even more eccentric brothers. Eccentric is a good word here.
