Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: Even though I did enjoy this book, I was disappointed in the way some of the characters stories were left hanging, such as Father Hurley's nephew. What happened to him? The character of Helen REALLY got on my nerves. But then, she was probably supposed to. Overall, though, it was a good read.
Solution: Positive
