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: Busy Buddy Kibble Nibble has been a great toy for my dog, but Tug-a-Jug was not.  Within 10 minutes, she had gnawed the "challenge" rope into 6 pieces.  Maybe it's good for an older dog but definitely not for my vigorously chewing 8-month-old puppy!
Example Output: Negative

Example Input: I opened the box to find a huge mess of chocolate all over the tray. Chocolate was no better than Hershey's and worst of all, it is imported from Hong Kong. I don't care to eat food made in China after all their countless product safety issues. Look elsewhere
Example Output: Negative

Example Input: I tried this before having normal red tea so I waited to review. The flavor still rings in my head it is earthier than rooibos tea and less frity. The color is that of muddy water, and it has the grittiness and viscosity of it as well. Well worth every penny.
Example Output:
Positive
