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: it does what it is supposed to do making you look slimmer in the waist area. my grandmother even notice it, and she didn't even know i bought it. It really makes you look smaller in that area of your body. I would most likely buy another one but next time in a small not medium.
Output:
Positive
