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 respect Asimov as a writer of science fiction. However after reading all of the Foundation series I wish it had more humanity in it. The book was overly complex. The characters did nothing for me. The Foundation series is over rated in my humble opinion. It falls in the category that I call dry sci-fi. Asimov's Robot series was better than this.
A:
Negative
