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: I suppose some people might rate this product higher as it is a great substitute for Bisquik, however I didn't like it because everything I made from it tasted like Bisquik.
Example Output: Negative

Example Input: My dog loves this food, and she has maintained her healthy weight for many years.  The vet is very happy with her general health, coat, and teeth.  Having the 16lb bag sent directly to my home without any shipping charges is terrific!  The 16 lb. size is not available in my area.
Example Output: Positive

Example Input: I ordered  Smoke paprika, unfortunately i received regular sweet. I called and spoke with a gentleman, who promised to send me the smoke paprika and apologized for the mistake made. Until today (1 month maybe 2 later) still haven't received anything or heard from the company. Very disappointed.
Example Output:
Negative
