The Confessions of Robert Crumb Movie Review
The film focuses on his life philosophies, his youth and ascent to fame (about which he is extremely humble), and of course, his comics. The film bears a certain resemblance to Crumb, with plenty of shots of his work (juxtaposed with his real life, of course), but it lacks the depth of Zwigoff's work -- namely because you can't really make a critical documentary about yourself.
Instead, Crumb offers up some gems -- a visual tour of the "perfect" female anatomy, some comments about Fritz the Cat, and various funny vignettes. On the whole, it comes off as not much more than a puff piece, but with R. Crumb as the subject, that's an awfully fun piece of puff.
