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: My 8 year old Great Dane was itching a lot with the Lamb meal from the big box stores. I started buying this (for cheaper) and he stopped itching. His coat is also looking shinier. I wish I would have discovered this years ago. It saves me trips to the pet store and money also.
Example Output: Positive

Example Input: McCann's Instant Oatmeal is great if you must have your oatmeal but can only scrape together two or three minutes to prepare it. There is no escaping the fact, however, that even the best instant oatmeal is nowhere near as good as even a store brand of oatmeal requiring stovetop preparation.  Still, the McCann's is as good as it gets for instant oatmeal. It's even better than the organic, all-natural brands I have tried.  All the varieties in the McCann's variety pack taste good.  It can be prepared in the microwave or by adding boiling water so it is convenient in the extreme when time is an issue.  McCann's use of actual cane sugar instead of high fructose corn syrup helped me decide to buy this product.  Real sugar tastes better and is not as harmful as the other stuff. One thing I do not like, though, is McCann's use of thickeners.  Oats plus water plus heat should make a creamy, tasty oatmeal without the need for guar gum. But this is a convenience product.  Maybe the guar gum is why, after sitting in the bowl a while, the instant McCann's becomes too thick and gluey.
Example Output: Positive

Example Input: I ordered Ka-me rice crunch crackers, plain. I received Ka-me gluten-free rice crackers, original, all natural.  Unfortunately, they have soy products in this cracker and therefore I can't eat it.  This looks different from the picture that came with the crackers I ordered.  Apparently I can't return the box of crackers.
Example Output:
Negative
