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 really love these snacks.  They are low in calories and fat while being high in protein, which is important to me because I am a vegetarian.
Example Output: Positive

Example Input: I love Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
Example Output: Negative

Example Input: Green Mountain Coffee, Nantucket Blend is my favorite coffee to use in my Keurig Brewer.  However, in this particular box, the coffee did not taste fresh.  Perhaps due to the large quantity in one box, it remained in storage too long.  At any rate, previous orders from other Amazon sellers, like az trading llc and pm trading, and smaller-quantity boxes from Amazon.com LLC were far superior.
Example Output:
Negative
