Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: First time I have purchased a DVD that had a 4 star+ rating and been disappointed. The front speakers and center channel were OK. The rear was terrible. The overall audio quality was the worst I have heard. Listened to it once and went back the next day thinking my set up had to be wrong. Tried two other DVD's and both were fine. Suggest you try something else.
Output:
Negative
