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 had been buying these treats for my cavachon for the past two years. He loved them.  The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats.  Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.
Example Output: Negative

Example Input: I loved this tea! It is refreshing and delicious with or without sweetener. A great buy! I would definitely recommend this product!
Example Output: Positive

Example Input: I normally rate whatever items I buy but rarely offer words of advice. Well, these things changed my mind. I love pork rinds. Usually I buy a tub of them from Sam's, but since I'm the only one in the house who eats them, they go stale long before I can make a dent in them. So I saw these, and the positive reviews, and thought, "Hey, that's the perfect solution!". It's a perfect solution all right...a perfect solution to get me to stop eating pork rinds.  I made the first bag, as per the directions. I had no problem with them crisping at all. They were perfect in that regard, nice and crunchy. But the taste is awful! I thought, perhaps, it was a bad bag. Nope. The second batch tasted just as terrible. I have no idea what they use to flavor them, but it tastes like a strange mixture of salt and soap. There's enough salt in them to kill a horse, which in and of itself wouldn't be so bad (I actually like salty things) but when combined with whatever garbage they dug out of their backed up shower and called seasoning, it left me hunting for listerine - or gasoline, whatever I could get my hands on - to get the taste out of my mouth. I'm still shuddering from it. If you like the taste of feet, go for it. If not, I'd suggest heading to Sam's to buy the wonderful tasting pork rinds we all know and love.
Example Output:
Negative
