Review: In a word, Lacking. Her style of writing left me unable to appreciate the underlying story which, as a result, I found rather vacuous and inauthentic. So much so that I felt compelled to come write a review of this book so others might avoid making the same mistake I did. No offence Patricia. 
 Polarity: Negative
True

Review: I agree, the CDs are a much needed help, since it would be impossible to pronnounce the Yoruba tones without the help of a native speaker. However, the design of the book is really poor and confusing. I have found several spealling mistakes in English and Yoruba. And the grammar explanations are very hard to understand.Unfortunately there are not many Teach Yourself Yoruba books that are worth it. This one at least provides basic vocabulary and pronounciation skills. 
 Polarity: Positive
False

Review: I enjoy reading about "unexplained phenomena". I really do. I love "real" ghost stories and the like. However, I prefer an author to take a very scientific stance, exhausting all possibilities. Keel does not. He's a "true believer" and that's the problem.Somewhere in the book he supposes that this mysterious Mothman could have been a man on a hang-glider. "Wow," I thought. "That could almost be construed as logical." However, he IMMEDIATELY debunks that theory with a statement to this affect: "But hang-gliders were not very well known at that time."*shaking my head*Whatever...the man needed to become familiar with Occam's Razor. 
 Polarity: Negative
