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 was never much of a hot sauce fan until I tasted Black Market Hot Sauce. I was listning to the radio one morning and the creater/owner was giving an interview, It sounded interesting. The D.J.'s were sampling the sauce and raving about it, So I picked up a bottle at the local grocery, It's so good ! I keep a bottle in the kitchen and an extra bottle on hand for gifts and for taking to potlucks,barbecues and party's. Happy to see I can buy it online at Amazon.
Example Output: Positive

Example Input: I was really impressed with this. There are many flavors, and quite a bit of heat. With this and your favorite brand of cocunut milk you can make some great Thai curries at home.
Example Output: Positive

Example Input: The cereals had a weird odour and also the colour is a slight tinge of greenish/greyish. Even though, the tins were originally sealed and expiry date is in 2012! Is there a production problem for the cereals? Perhaps amazon.com should do a sample check! This is a serious problem and should be investigated immediately as the cereals are meant for our dear babies!
Example Output:
Negative
