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: Woeber's Hot & Spicy Mustard is oh so good!  I'll buy another case when this gone.  Makes a great gift as well!
Example Output: Positive

Example Input: This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!
Example Output: Negative

Example Input: The chips were great...for the first few bags. However, after the first bag or two, I noticed that the remaining bags were damaged. There were holes in each bag and black, sticky stains on the outside. Other reviewers who bought around the same time that I did are now claiming that they found rodent holes in their bags of chips.  The chips came in a sealed Kettle box, so it's hard to say who screwed up. But someone somewhere screwed up. These chips were a health hazard before the holes in the bag. Now? It's like a game of roulette.
Example Output:
Negative
