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: Thought I was getting a really good buy on these until I read the label. The dosage amount of Glucosamine/Chondroitin is vague. It appears I need to give my dog an entire bag to get him 500 mg of glucosamine. Too expensive for me. The dogs love them, so if you want to give them an expensive treat they'll love, go for it. If you are trying to get a preventative dose of glucosamine in a treat look elsewhere.
Example Output: Negative

Example Input: I was disappointed to receive Earth's Best Organic Snakin' Fruit Rings Banana because it hurt my child when she bit into the hard and stale treat.
Example Output: Negative

Example Input: I just cannot understand the high praise these chips have received! AGREE. I ordered the Sea Salt&Vinger packs and am very disappointed. Ver weird Vinegary awful taste. The salt and vinegar especially tasted gross! I took one bite and had to throw the bag away. Agrre. Now I'm stuck with a bunch of 23 bags of chips that I'll never eat.
Example Output:
Negative
