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: My english teacher assigned this book, one I would never read on my own. I am a 16 year old and I enjoy reading. But this book, while it does have a few good points and messages, is incredibly dull. The points are hard to get and I only understood the points after we had discussed them in class. While this book has a rather good story it's concealed by endless symbols and references, I suggest the cliff notes version!!
Solution:
Negative
