Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Book is over 600 pages and the print is so small it was difficult for me to try to read so I returned it. Perhaps if it ever comes out on Kindle I would try again.
Example Output: Negative

Example Input: This isn't the original art for these books. They hired a cheap hack to make the illustrations "less scary". The original had a better artist and better illustration. Dont waste your time on this pussified version.
Example Output: Negative

Example Input: I am the author of an article for "The Skeptical Inquirer" about the origins of "The Mothman Prophecies." The article, which appeared in the May/June 2002 issue, also may be read at the CSICOP web site.There, I describe the highly dubious role Gray Barker played in the background during the events surrounding this now-well-known West Virginia case. Barker was responsible for at least one telephone call (and possibly more) to John A. Keel and others in an attempt to generate interest in the Mothman and UFO accounts that were rampant at the time.Those who wonder what to believe about "The Mothman Prophecies" will gain greater insight into the situation by reading this article -- but only if they truly wish to understand that there is indeed "more to the story."
Example Output:
Negative
