Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: This DVD could not be played all the way through. I tried skipping past the "bad part" but no dice...it simply would not play. I was really looking forward to this video and will not buy from this seller again. The only good thing was that my money was returned (less the handling fee!) Feel like I was penalized for using this seller.
A:
Negative
