Query: Why was this written?

Seems odd to write a book about someone of whom the author does not seem a fan. Not only is the tone entirely loathesome, it is riddled with fabrications and loosely based hear-say. Not only was it poorly researched, it seems as though in many areas the facts were blatantly overlooked, omitted. The author quickly loses credibility with anyone who has access to verifiable facts about Buster Keaton's life.This book was a peculiar waste of time and energy for the author, and more-so for any potential reader.The beautifully done (and seperately researched) discography is the only reason this book received two stars from me. (Borrowing it from the library will clear one's conscience, if one needs access to the thorough discography.)
