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 disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.
Example Output: Negative

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: These are wonderful!  Exactly like the originals, only in miniature form.  Delicious and crispy and the wonderful Amaretto flavor!  Rapid shipping from the seller as well!
Example Output:
Positive
