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 was offered the opportunity to taste this product because of Vine. I would not normally purchase this type of product, so my review and opinion will be biased in that regard.  I'm not a big soda drinker, I'd just rather drink water or coffee. I will occasionally drink a diet soft drink, usually Diet Pepsi or Diet Coke.  Did you know that a single 12oz can of Coke Classic® has 140 calories and 39 grams of sugar? This 8oz can of Switch has 140 calories and 34grams of sugar. And this is healthy? 4 ounces less is size, same caloric content and more sugar per ounce that Classic Coke. OK, so it's not "added" sugar, but still, that's a lot of sugar. 100% Orange juice, 8 oz, has 120 calories and 28 grams of sugar.  The can says it is "Orange Tangerine" but in fact the contents are #1: Water #2: Concentrates of Apple, Grape, Tangerine, Orange, and Acerola juices. Then they throw in some "gum acacia", "natural flavors and colors" and some "ascorbic acid(vitamin C)". And as a little surprise bonus, they have added "soy". Soy?  I asked my wife to taste this product with me. I poured the drink into two glasses and we both took a sip. Her reaction was swift and strong... she hated it. I agreed with her. It was for me, sickly sweet and left a sugary aftertaste in my mouth. Not only that, but the taste was just nasty. It didn't taste at all like orange or tangerine to me. It just tasted terribly sweet with an undefined cirtus something taste. The carbonation did not add anything positive to the experience. Neither of us finished drinking our 4oz portion. It went down the sink.  I would not purchase this product in the future and if I could have given it 0-stars, I would have. It's that bad.
Example Output: Negative

Example Input: Love these snacks! They're a little bit sweet, loads of crunchy almonds. Am looking forward to trying the other varieties, too.
Example Output: Positive

Example Input: I was a huge fan of canidae, but beginning about a month ago, the company changed the formula to cheaper raw materials, smaller bags, and worst of all outsourced manufacturing to Diamond pet foods (yes, the same company linked to multiple recalls in the past). Please do a search on google/consumeraffairs.com. I will not be giving my dog this brand anymore. It's the same mass produced garbage as is iams, eureka, etc.
Example Output:
Negative
