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: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Example solution: Positive
Example explanation: It's a positive review because the owner of the dog is satisfied with the product and mentioned that their dog appreciates the product.

Problem: Disappointing. I went to a lot of trouble to buy these, as I thought it would be impressive and novel for guests when drinking champagne at Christmas. No-one had any useful comments to make, some left half of the champagne and the flowers, although encouraged to eat them.It was a waste of money and champagne should not be interfered with, maybe better in lemonade!
Solution: Negative
