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: Sorry to all you champurrado fans, this is not the real deal, but an artificial version, and WAY too sweet. Please compare to others 'hecho en Mexico', and get yourself a 'molinillo' while you're at it! ps: I use almond milk to make mine!
Example Output: Negative

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: Salt & vinegar chips are my favorite flavor so I think I've tried every brand out there.  These are by far the best.  I also like them because the sodium content is not very high like some of the others and they are not excessively greasy.  They seem to have the right balance of the salt and vinegar taste.
Example Output:
Positive
