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'm a big black tea drinker and have tried a lot of different brands out there, and I find that PG makes the best black tea. It's nice and strong, not like crappy Lipton black tea. We've been loyal to the PG brand black tea for over a year now - it's a little pricier than other brands, but definitely worth it if you enjoy black tea.
Example Output: Positive

Example Input: These were NOT good. They were hard and chewy and my kids wouldn't eat them. That says a lot b/c my kids will normally eat anything!
Example Output: Negative

Example Input: "The Food and Drug Administration (FDA) is again cautioning consumers that chicken jerky products for dogs (also sold as chicken tenders, strips or treats) may be associated with illness in dogs. In the last 12 months, FDA has seen an increase in the number of complaints it received of dog illnesses associated with consumption of chicken jerky products imported from China. These complaints have been reported to FDA by dog owners and veterinarians."
Example Output:
Negative
