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: The Prepara Herb Savor Pod is advertised holding asparagus. That was why I purchased it, thinking it would be good for keeping asparagus fresh. In reality the pod will hold very few spears and they would need to be quite thin and short.  The ad is misleading. I'll keep it for storing herbs, but asparagus is out of the question.
Example Output: Negative

Example Input: Caviar taste awful. Maybe it's because I bought from a cheaper brand or maybe because cavier is just bad no matter who you buy it from or how much you paid for it? Why do people like to waste money on these things?
Example Output:
Negative
