Example Output: Negative

Example Input: 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.
Example Output: Negative

Example Input: This is the first book by Alastair Reynolds I have read. I must say I was disappointed. The idea behind the book is interesting. But Reynolds' writing is pedestrian at best. The pacing is terrible. The characterizations are thin. The book drags for hundreds of pages, then falls apart in the last 50. It seems like the editor got nervous at the length and told AR to wrap it up quick-smart.I would read other books by AR if they were given to me, but I won't be buying any others.
Example Output:
Negative
