Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I didn't make it half way through the book before I gave up on it. It just seemed to go on and on and on.... I usually like Mercedes Lackey, but every once in a while, she makes a bobble, and this was one of them. I think the book whould have been a lot better as either two books or one greatly pared down book.
Solution:
Negative
