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

Example Input: I just got my 2007 edition copy of "Interpretation of Dreams" in the mail so I haven't had a chance to read it. So this rating is only on the particular edition that is published by NuVision. They did not include an index or any information about who translated this version. Also, the table of contents is nearly worthless; no detail what-so-ever about the chapters, not even titles of the chapters, just Chapter 1 etc. and a page number. Even though you may think a newer publication is better, this one is much much worse and more expensive. Go with the 1980 publication. I'm returning the book to Amazon (who gets 5 stars for customer service!)
Example Output: Negative

Example Input: Paxton Quigley's book is a compliation of parts of other books on firearms self protection. It's a bit overdone, and probably would scare the average woman thinking about protecting herself. Women seem to have special problems protecting themselves. They usually do not want to hurt anyone, and they will do all most anything for a baby or a family member before they will do anything to protect themselves. However, women that are able to continue to practice with a hand gun, usually become quite proficent. They know that they don't know, and they listen to instructions. Most men think they know it all already.
Example Output: Negative

Example Input: This machine does a decent job of cleaning when it works, but it breaks way to easily for the price, and its not built well enough to justify fixing. Too many cheap plastic parts. Consider it to be disposable if you buy it.
Example Output:
Negative
