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 hate giving classics bad reviews. This book was not for me. Nothing captured my attention and I found that I had to force myself to read it. If it had been any longer I would have stopped. It did catch my interest a little in the end, but not enough to redeem the book in any way.
Solution:
Negative
