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: Received DVD's with no issue. The problem was that they were formatted for a region other than the United States. This is strange to be due to the fact that they were shipped from an American address to an American address. Amazon refunded my money with no issue.
A:
Negative
