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: This book was well reviewed and I was very disappointed. Even if it's written for poor readers, does it have to read like Dick and Jane? Children are young, not simple-minded. Give kids real literature or they won't keep reading, they'll plug in to the media.
Solution:
Negative
