Notorious comic artist Robert (R.) Crumb is definitely the most well-adjusted member of his immediate family. Fairly early in this documentary we are introduced to his two sibling brothers (mom is briefly viewed as well) and it becomes apparent that his childhood was less than rosy. Crumb and his brothers drew mind-blowing comics as an escape from their chaotic childhood, but it was only R. who would turn his talents into a means of permanent escape, while his oldest brother remains at home with his mom and never leaves the house, and his youngest brother is holed up in a seedy residence hotel and spends his days sitting on a bed of nails (I kid you not.) Whether or not you’re a fan of Crumb’s work, this is an amazing documentary about an eccentric individual and the world of underground comics.
