This is simply a perfect documentary. I cannot find any fault in it or room for improvement, unless it would be to make it an even longer sampling of Keaton's skills. Buster Keaton was a unique master of physical comedy on film and this documentary is a worthy examination of Keaton's life. The music is wonderful. When I see Keaton's films now I wish the music from this documentary was playing with it. Everyone should see this documentary. Many would be surprised at what silent films had to offer.
