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: I was very unhappy with the number of typographical errors not only in this book but in all of the books in the series. The story continues to be a favorite of mine, but the errors decreased my ability to totally enjoy the digital copy. In some places I am not sure I would have known what the word was if I were not familiar with the books already. It has made me a bit cautious about buying other digital books. I was looking forward to building my digital library and clearing out some space by getting rid of hardcopies. Now I am not sure I will.
A:
Negative
