question:
Review: What a disappointment. This book is about 50% self-centered travelogue and 50% teasers about the mysteries. I expected a book full of archeological information about cities and cultures that have long since disappeared, but instead got embarrassingly ridiculous chit-chat and superficial explanations. I wanted scientific information, not a book that tends to explain most of its mysteries via levitation and alien beings! 
 Polarity: Positive
answer:
False

question:
Review: This book is typical Keel--chock-full of anecdotes, skewed information, speculation, hoaxes (many of Keel's "weird" experiences in the case were jokes perpetrated by Gray Barker)--all presented as factual reporting."Mothman" does not exist. Several writers--most notably Joe Nickell--have thoroughly debunked the incident. But true facts have never stopped Keel.I'm a fan of Keel's writings, but you have to take them with a grain of salt. This is not one of his best efforts, and it rankles me that he positions himself as a serious journalist. 
 Polarity: Negative
answer:

True
