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: Behind the Eyes is slightly different from Amy's two previous releases; BTE is more mature and it gets better and better the more one listens to it. "Turn This World Around" is my favorite on the CD, but the rest of the material is also great.
Solution:
Positive
