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 have tried many many many different brands. I also did my research on what's the best for my Dane and most of it is expensive. I found this to be very good quality and a good price among Chicken Soup and Canidae. My GD loves this he eats 7-8 cups a day and he would love to eat more. He has a shiny coat, no allergies and his sensitive stomach thanks the food. I highly recommend this. But I am buying it somewhere else a little cheaper and 2 day shipping. ;)
Example Output: Positive

Example Input: These were NOT good.  They were hard and chewy and my kids wouldn't eat them.  That says a lot b/c my kids will normally eat anything!
Example Output: Negative

Example Input: You CAN taste the flaxseed in these whole-wheat muffins and it's a great taste.  Good chocolate flavor and texture.  I add chopped walnuts.
Example Output:
Positive
