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: Enjoyable tea with a refreshing taste.  The 16-count Pack of 6 represents an excellent buy compared to store prices.
Example Output: Positive

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: This is suppose to be a "healthy" snack. Then they shouldn't sneak artificial sweeteners in. I do like the taste, but I'm going to have to go with another flavor. I got the applewood also and it looks like it doesn't have sucralose. So just be aware that different flavors will have different ingredients.
Example Output:
Negative
