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 bought this "flavor" and the raspberry pom and while they are consistent, it's useless.  If you plan on making a pitcher of tea, forget it, it takes 4 packs for 64 oz and is still very, very weak in flavor, and it must be consumed in 12 hours (so they say) so you're much better off brewing your own.  However, if you're idea is to "stash" this in your purse (for the ladies) or pocket (for men, which would be weird) it's still misses the mark. One packet does very little for flavor with 16 oz of water so you'd have to use two, and WHO drinks just 16 oz of water when out to eat or something of that nature? Also, with only 8 to 12 packets in a box (depends on flavor, who knows why?), that gives you 4 to 6, 16 oz drinks for $3. Not sure it's worth it at all, I'd rather drink lemon water when out than this.
Example Output: Negative

Example Input: I first drank this tea at Naniboujou Lodge on the North Shore of Minnesota, and bought a small packet up there. I was hooked, so after I had drunk the first bit I bought I wanted to get more of this tea ASAP. Was glad to see it for sale in such a high quantity here. I used to be a coffee drinker, but I much prefer tea -- specifically, Ashbys Afternoon Tea -- now, and I just gave away a bag of coffee I'll never drink. I never quite got why British people are so into tea, but -- whether this is a typical British tea or not, I don't know -- I now see why they'd build their afternoons around a high-quality tea like this one. Sublime.
Example Output: Positive

Example Input: My boxer enjoyed the treat, though after eating it she drank a bowl full of water.  Maybe it had a lot of sodium.  The real surprise came the next day though when she suffered a loss of bowel control; she's never went #2 in the house since we got her over a year ago.  Afterwards, we took her on a hike and she couldn't seem to stop "going", had 7 bowel movements on a 2 mile hike; and they were very watery.  She's still not acting back to her normal self.  I guess it makes sense; I wouldn't trust a butcher from a group of people whom I know to be cannibals, why should I trust dog treats made in countries that eat dogs?
Example Output:
Negative
