This is strictly a tourist rag. Don't waste your time. If your looking for a basic introduction to Voodoo, try Laennec Hurbon's Voodoo: Search for the Spirit; Voodoo & Hoodoo by Jim Haskins; Sallie Anne Glassman's Vodou Visions; Leah Gordon's Book of Vodou or even the Complete Idiots Guide to Voodoo.

Ex Output:
Negative


Ex Input:
I didn't like some of the plot twist, of a former leader of the Autobots but other than that it was pretty good.

Ex Output:
Positive


Ex Input:
Hawthorne was a excellent writer for the 19th century, however, this book is very slow and often has no dialog for over a chapter. The descriptions get very long, boring and tedious. As you read this book your mind starts to wander and you can't remember what happened for chapters at a time. The only was I was able to get through it was by reading Cliffs Notes then the book.

Ex Output:

Negative
