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: The story itself was interesting, but the book is not well written. The author pads out half her sentences with adjectives and adverbs that are meant to add feeling that she apparently doesn't believe the facts will convey. She also seems unaware of the many cliches she uses. A potentially compelling story, written in an irritating, amateurish style.
Solution:
Negative
