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: in my opinion these are heads and twos above any pickle that you normally find at your local grocery store.  a lot of nice, sweet, pickle flavor.  I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.
Example Output: Positive

Example Input: I like strong coffee, but I don't want it to taste burnt or have an acidic after taste. Caribou Coffee's Mahogany is full bodied with a nice balance of dark notes and acidity.  It's one of my "go to" coffees when my favorites like Coffee People's Wake Up Call are out of stock.
Example Output: Positive

Example Input: This is the best pancake mix!  I've sent this to several people, and they all love it. The two-pack makes a nice little gift.
Example Output:
Positive
