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: These were nasty, they were so greasy and too rich for my blood, plus they lacked major flavor, no spicy jalapeno flavor at all.  I was so dissapointed in these chips, I am always hearing great things about these chips but I am telling you, yuck yuck yuck.  Give me pain chips any day.  Maybe there is a better kettle chip brand out there but I am staying clear from these chips. I wish I could give these zero stars if I could.
Example Output: Negative

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: What's in this stuff?  Where's the list of ingredients?  I don't eat anything unless I know and approve of what's in it.  For example, although this product's description says it contains no sugar, it does not say if it contains any artificial sweeteners, which are also bad for you.  For one thing, aside from tasting awful, artificial sweeteners often cause horrendous intestinal cramps and diarrhea.  In addition to having long ago given up the eating of sugar and sugar in all its guises (e.g: "natural" cane juice, fruit juices, "raw" sugar, "organic" sugar, etc.), I also stopped ingesting artificial sweeteners of any kind.  So, what's in this stuff?
Example Output:
Negative
