Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I am not usually so critical, and I must admit I read several of the books years ago, but I finally put them down without reading the rest because there was just too many descriptions of sex in them. The detailed and varied descriptions were simply unneccesary for a book that is touted as a "must read" for women as young as 10!
Output:
Negative
