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 first tried Britt dark roast when I was In Costa Rica. It has a lot of rich flavor, but it is not bitter at all. I've bought it by the case ever since. It's really no more expensive than those "gourmet" brands you find at your local store. This is simply the best coffee I've ever had, and I've tried many supposedly special ones over the years.
Example Output: Positive

Example Input: Looks like and tastes like chocolate colored water. No chocolate flavor whatsoever, this was a complete disappointment. I got the hot chocolate k-cups from swiss miss instead. How people can be giving this product four and five stars is astounding to me, is the Amazon ratings system being gamed for this product?
Example Output: Negative

Example Input: My dogs who will generally "play" or destroy any toy had no interest. I tried placing everything short of hotdogs into the jug with no avail.
Example Output:
Negative
