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 is a pretty cool set. The only thing wrong is that is should be a little taller like in the movie. This set really recreates the tower in the movie. The only thing wrong is the door. It should be like a prison door like in the movie, not a wooden one. Some good things about this is only one of two sets that have buckbeak, one of four sets that have a dementor, and only one of two sets that have Sirus Black. I RECOMEND THAT YOU BUY THIS!!!
A:
Positive
