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: Got this item on a one-day-only sale on Amazon.  Love having the single-serving portion as I am following WW plan.  Only 3 points plus per serving.  Tasty and on the same line as the Special K crackers.  The variety is nice to have and the box will last for awhile.  Cheddar and BBQ are my favorites.  Try them...
Example Output: Positive

Example Input: I have been feeding this to my Standard Poodle for quite some time. It was recommended by a local dog day care/grooming/training center called Great Dog Shoppe in Seattle. They are VERY specific about which foods they suggest and sell. It must meet certain standards of nutrition or it's no-go. My poodle loves it, but even better, I offered some to my cousin's finicky poodle who "just doesn't eat when she's away from home". She gobbled it right up and asked for more. When I compared the contents of Newman's to her brand (which was suggested by a breeder) there was NO comparison. Newman's Own is far superior. I get it via "subscribe and save" so I never run out, I save over the store price and it's delivered right to my door. What could be easier?
Example Output:
Positive
