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: Terry Pratchett's other books are a lot like well painted homes. There are several layers. "Small Gods" is like inviting over your friends to paint. There is one uneven coat of paint and they left masking tape on all of the edging in an unsuccessful attempt to miss it with their paintbrushes. The ending of the book (and middle and beginning too if truth be known) left me with the same vague feeling of dissatisfaction as when I realized that to get the place properly painted I would have to have another seperate group of friends and throw another 'paint party'.
Solution:
Negative
