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

Example Input: Author doesn't believe in any biological interventions and feels you should just accept you kid's disability and get on with it. Needs to spell check his work also.
Example Output: Negative

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: This series influenced me as an artist in profound ways, and it was all because of Stephen Gammell's illustrations. I remember staying up late at night and just absolutely loving the how terrified it made me feel. It's very sad to me that children today aren't going to be able to experience the same thing because Gammell's illustrations have been stripped out and replaced by inferior, less emotionally impactful illustrations.I'm just happy that I went out of my way as an adult to buy multiple compies of Gammell's version before they were pulled from shelves.TO THE PUBLISHERS: Please make Gammell's version available to the public, so parents can make the choice about which version to buy their children. After over 3 decades, it would be so sad to see Gammell's version just disappear...
Example Output:
Negative
