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 recieved a Keurig K-Cup Brewer for Christmas with sample cups of coffee and tea but no cocoa so I tried this brand and I like them but I haven't tried other brands yet to compare with. I would buy these again until I find one I like better.
Example Output: Positive

Example Input: Oh my gosh, is this good! Like most people, I've been eating ketchup my whole life and never really thought anything about it. Then Hubby brought a jar of this home. The tomato flavor is amazing. I will never buy store ketchup every again.
Example Output: Positive

Example Input: I will never again even CONSIDER a dog food with corn, wheat or soy in it. Grain has no place in a dog's diet!
Example Output:
Negative
