Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: Once again I wish I'd paid closer attention to the more critical reviews ... This product is far too rigid and thick. With the beads and other material in the center, it does not bend at all, and it's painful to try to use. There are also rigid bumps around the too-large tip (which is 1.5 inches wide, 5 inches around) that make it even more painful to insert. I've used the similar - but far more realistic - Doc Johnson product (beads and rabbit, but none of those bumps, and a more natural tip and girth) and hoped it was the same thing, but it isn't. On the upside, it's as quiet as the Doc Johnson product - and it'll be even more quiet, unused, in my nightstand. Waste of money.
Solution:
Negative
