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

Example Input: I've read all of the Night World books, and this is a great book, but I must say, it's not L. J. Smith's best
Example Output: Positive

Example Input: This completely predictable novel seems more like a beginner's attempt of writing a book rather than an American classic. The author treats the readers as if they completely lack a brain by stating the understood and by completely beating concepts to death (note the reference).
Example Output: Negative

Example Input: The chilling story as told by detective Bugliosi will scare and shock you to your utmost. There is an eerie sense all about you that keeps you wondering how such diabolocal people could exist in this world. In all its gorey details and brutally honest depiction of the Manson "Family" Bugliosi does not shield the reader from the horrrid acts committed. He is forthright in his personal fellings toward the murders and his perception of the Manson "Family" including their theology that "Helter Skelter", the final war between the balcks and the whites, is the most outrageous in all of history, which made everything in connection to the murders just as strange.
Example Output:
Positive
