Definition: 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.
Input: I was disappointed in the unpleasant flavor and dry texture of Nana's Chocolate Munch Cookie Bars. To me there was an odd artificial almost chemical like after taste in them that cocoa powder can't even cover up. I threw away the entire box after tasting the first bar.
Output:
Negative
