Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I enjoyed the first Transformers immensely. It was quirky, fun and exciting. I'd heard Dark Side of the Moon had recaptured some of that magic. And at first it mostly did. But then, like so many big budget action movies it devolved into noise, machines smashing one another one frame after another, after another, after another... And at over 2.5 hours in length you reach a point where you stop caring. You could edit out a third of the content and it would have been a better movie.
Solution:
Negative
