You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: This is a cute product to use in place of sprinkles - the bright colors of candy coating look great, and the chocolate center keeps them from being overly sweet.  However this price is roughly double what you pay at Michael's (or Marshall's, when they stock stuff like this). Plus you can get the same product but in a 16 oz bag on Amazon here: http://www.amazon.com/CK-Products-Rainbow-Candy-Coated/dp/B00375LAO0/ref=sr_1_1?ie=UTF8&s=home-garden&qid=1300131716&sr=1-1. Comes with Prime shipping too!
Example Output: Positive

Example Input: The rice flour in it is a crude gritty grade (cheap?). If you've ever used Thai rice flour <a href="http://www.amazon.com/gp/product/B000EYC096">Thai Rice Flour - 16 oz</a>, you know that rice flour does not need to be this unpleasantly gritty.  I tried compensating for the grit by using Bisquick Gluten Free to make Johnny cakes since the cornmeal is sort of gritty. But sadly, after you chew you are still left with this unpleasant grit like fine sand in your mouth.
Example Output: Negative

Example Input: After eating TANG's chocolate and double-chocolate cookies, all other cookies will taste like expired, tepid dogfood to you. Her cookies will enhance your life in ways you never dreamed possible. Tim Horton's, Timothy's, Second Cup, Starbucks, Treats and those horrid packaged cookies at Zupas are just pathetic imitators to the grandeur that is a TANG cookie. HER COOKIES ARE DA BOMB!!! A+++++++ Hawt damn!
Example Output:
Negative
