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: Somebody from higher places should have stopped Mr. Higgins and the publisher from putting this book on the market.Its quite disturbing to see the absence of integrity and sense of responsibility in providing a joy of reading to the public.All along, I had fight off the growing urge of disposing this disastrous novel only because the shipping charge cost more than the book itself.Yet, once I overcame my frustration and finished the book, I regretted not heeding to my senses.Its obvious that Mr. Higgins had no heart in writing this book, and he made no effort in showing creativity with words.I was about to scream my head off when he kept rehashing the same phrases (e.g., browning with carswell silencer) over and over again in every single chapter!!This book made me a true anti-Higgins....
Solution:
Negative
