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 concur with previous reviewers in that these muffins have such a bitter taste! I also bake often and I'm certain it wasn't me. My gluten-eating husband didn't like them either. They were also dense. If you are looking for an apple cinnamon flavor and need a mix, you might be better off using Pamela's Baking Mix (which is awesome!) and adding apples and cinnamon to it. The muffin recipe is on the back of the Pamela bag. In conclusion, I don't recommend these; they were really disappointing.
Example Output: Negative

Example Input: We have been giving our 100 pound shepherd/lab/collie/husky mix Hip Action since he was a pup. Our vet believes this is realy going to help him prevent all the hip problems that shepherd's usually have. Eventhough I cannot buy it locally, I make sure to buy it on line so my boy will remain healthy and happy!
Example Output: Negative

Example Input: Good thing I got this from the bargain bin or I would really be perturbed. Whatever the claims, this mix has no chocolate flavor of any kind. A more correct description would be Coconut flavored drink mix. Apparently the 10 oz rating is including the weight of the "cauldron" because there's no way there was 10 oz of product inside. You might get three cups of "hot chocolate" per container if you like the "flavor" really mild. It really wasn't worth the price I paid and certainly not the inflated regular price. Two of the three cauldrons were dented heavily so those won't even be much use as decoration. Look for a better brand.
Example Output:
Negative
