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 has no plot, and is so absolutely predictable that I had to put it away without finishing. Sean Dillon's character is getting so tired and his invincibility is sickening. A very poorly written book. The only good thing about this book is that I got it from the local libary and did not spend any money on it. Mr. Higgins, it's time to retire Sean Dillon and maybe spend more than 2 weeks on writing a book??
Solution:
Negative
