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

Example Input: I think this is a case of my expectations being too high. I was so encouraged by the great reviews of this product, I really was expecting a miracle. After only wearing this twice, it is stretched out. At first, I thought perhaps it would regain it's shape after a few hours but nope! It's no better than a cheap, fashion corset. It will smooth things out so there's less bulging under the clothes but I was looking for a real "waist trainer", something that would go on tight and STAY tight. Considering I found this product when I searched specifically for "waist trainer", I would say the claims of this product are misleading. It is shapewear, it is NOT a "cincher" or a "trainer".
Example Output: Negative

Example Input: Jack Higgins may not be running out of his fascination with modern weapons, fine dining, glamorous women or the IRA but he appears to be slipping on plot and character development. Sean Dillon makes Doc Savage and Dirk Pitt look like pikers. And this curious extension of gentlemanly methods for attempting to kill one another -- sending a crazed assassin and then both sides meeting later at the Savoy to exchange notes -- strains credulity.Higgins has done some first-rate work. Had this been published twenty-five years ago, this might have made a difference. It wasn't and it doesn't.
Example Output: Negative

Example Input: I ordered textbooks for my child's high school classes. I was pleased to receive the books within a short period of time. Also, the books were all in great shape upon arrival! I felt each book that I received was accurately described.
Example Output:
Positive
