Query: More scholarly claptrap

When a man is born who only ever wanted to make people laugh, why would someone write a book that manages to suck every interesting thing about him and his work into a laborious, scholarly void? Reading this was as interesting as watching wood warp. The best book regarding this comic genius - "Buster Keaton and the Dynamics of Visual Wit," by the amazing George Wead, is impossible to find, but this junk is available in the discount bin. More's the pity for anyone who would like to read about Buster.
