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 was really disappointed in this book and surprised that so many people think it is a wonderful story. It was such a depressing story and reflects all of the worst things about the way women were treated in that time. I don't think this story had any redeeming qualities and very few likeable characters (even Tess was quite irritating at times with her pride getting in the way of asking for help to make her life a little easier).
Solution:
Negative
