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: Our family has liked every other flavored we have tried (BBQ is the best). We like sweet potatoes so we assumed would like these pop chips.  I was wrong, no one in the family likes the sweet potato pops chips.  I highly recommend you go to a store that sells the sweet potato before deciding on purchasing a large quantity.
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: I didn't mind paying the $20+ a bag because my dog loved them. These are so expensive that I didn't look on the bag to see where they were made until ANOTHER recent recall on Chinese dog treats/food that was killing dogs....when I looked at the Happy Hips bag, I was pretty ticked off to see that these are made in China.  I used to joke that my dog was addicted to these, but now I am actually a little concerned that there may be some addictive substance in these Chinese "treats"
Example Output:
Negative
