Query: Spotty Research

I am in the middle of this book just because I hate to start something and not finish it and although it appears to be exhaustively researched and written I have come across some glaring errors that throw the whole book into question for me: in the photo section she captions a photo of Lillian with Hollywood producer Hal B. WALLACE - shouldn't it be Wallis? And in the section about Lillian's first stay in Hollywood she lists Mae West as a "Kansas City runaway who starred in Hell's Angels" - doesn't she mean Jean Harlow? These are such simple facts to get right it makes me wonder about the rest of the author's research and fact checking skills . . . So I am giving it two stars for now . . .
