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: Only Pom.Mol.I've ever used but this seemed to have the same flavor the Chef came up with for a pomegranate relish for fish. It seems to have a bit of a brown appearance though where the one the Chef used was a brighter red color.
Example Output: Positive

Example Input: I adopted my dog about 6 months ago and he had digestive problems that the vet could find no cause for. He would get diarrhea with mucous in stools regularly. His stools would vary from constipated to unformed soft stool. I decided to switch him to a better quality food and did a lot of research. Newman's Own had all the qualities I was looking for, so I switched him to it gradually - 1/2 Purina One and 1/2 Newman's Own at first and gradually more Newmans' Own in the mix until finally 100% N.O. Ever since switching about six weeks ago, he has not had constipation or loose stools. I also don't hear his tummy roiling after meals like before. And despite what a few reviewers have written, the chicken and beef used in the pet food, while not "organic", is "natural" and raised without hormones and antibiotics.  According to [...] ingredients list: "Natural Chicken - Raised without growth hormones and antibiotics and fed only a 100% natural, all-vegetable diet, the chicken meat provides amino acids essential for muscles, hormones, enzymes, antibodies and structural and protective tissues." Also, the beef is free-range anad range fed w/ no hormones & antibiotics.  For me the evidence is clear - this is good quality food, my dog loves it and I love that when I buy Newman's Own products, the royalties go to charity!
Example Output: Positive

Example Input: These cookies were ok, just ok.  I may have been inclined to give them three stars had they arrived as whole cookies, every last cookies was broken.  I understand this is probably due to poor packaging.  The consistency was a bit grainy and dry though.  And milk did not help.  Next time I'll purchase a chewy brand or Mrs. Fields.
Example Output:
Negative
