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: Product was never received nor money returned. Four requests have been ignored. I will probably never again order anything through Twang or from Amazon. Also, I will spread the word about these sites.
Example Output: Negative

Example Input: I'm such a coffee snob that I source from specific farmers in Ethiopia. I say this so that people will understand I don't drink grocery store coffee. This Puroast low acid stuff? Flavorless. No body. No "coffee-ness" to it. It tasted like vaguely coffee-flavored water. It's caffeinated, so it's got that going for it. I'd rather take 50 Tums and drink good coffee though.
Example Output:
Negative
