Best two reviews:
1) Time Out New York - The oft-hilarious push-and-pull between director and subject - Williams wryly notes that the film is turning into "the Steve and Paulie Show" - effectively hacks away at the celebrity-enthusiast divide. By the end of this perceptive dual portrait, both men are content to merely be human. (Rating: 80) Read Full Review >
2) The Hollywood Reporter - The film has a winning combination for all sorts of platforms as the story is highly intriguing and the music speaks, or rather sings, for itself. (Rating: 80) Read Full Review >

Worst two reviews:
3) Village Voice - Johnny Carson loved him, and Williams had the credits to back himself up: As with Jimmy Webb, you could probably sing many of his songs without knowing that he's the author. (Rating: 70) Read Full Review >
4) Slant Magazine - The film too often undercuts its goals by indulging its director's need for self-affirmation at the expense of the movie's far more compelling central subject. (Rating: 63) Read Full Review >
