Query: Do NOT buy this book

Absolutely horrid, poorly-researched, extremely judgmental "book" about an admittedly complex genius who died much too young. "Sunshine on My Shoulders" is "banal"? In 100 years, people will still listen to this song. In 1 year, no one will remember this incredibly bad author. It is written on the level of a high school newspaper critical essay...no, change that. Elementary school newspaper. Wow...this book is bad.
