Query: BAD BAD BAD!

Essentially all this book is is a review of other books and movies about exorcism. I was excited when I bought this book I thought it would be very interesting, it is not! The author is the Ebert of exorcism book and movie reviews. He seems to have no real stories of his own. All he is doing is talking about others personal experiences with exorcism. Reading this book is like reading a college term paper. While there are a few fascinating stories these can quite simply be found in the books in which the author of American Exorcism took them from!
