Given the task definition, example input & output, solve the new input case.
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
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: Well, I might have agreed with the other reviewers if I hadn't ordered "Strength Ball Training" by Goldenberg and Twist at the same time. This book seems very amateurish by today's standards. It's a thin paperback with hand-drawn sketches. Maybe this was considered okay back in 1991, but this is 2008. SBT gives you all of the exercises in this book plus many more, updated with recent training science background, illustrated with photographs of actual people, plus a DVD with videos illustrating many of the exercises! And it's the same price! Come on, get into this century. Amateur productions like this one just don't cut it anymore.
Output:
Negative
