One of my favorite documentaries of all time. Watching it a second time, I paid closer attention to Charles Crumb's art; he was Robert's brother and his art was incredible, too. I think that R. Crumb was more technically impressive, or more of a slave to his compulsions to draw, but Charles' ideas were very weird and unique. David Lynch is dripping into every frame. He constructs a very familiar looking slideshow of amazingly technical art right next to heinous shit that is incredibly well drawn; Spliced into the movie every so often like the dick frames from Fight Club. He drew a kind of incredibly complicated and asymmetric skyscraper free-hand and that blew my mind. His hatched shading technique also blew my mind. Lots of mind blowing going on in this one.
