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: These pop chips are satisfying and good for a snack, but not what I expected. They do not taste as good, crisp or as light as the Weight Watchers brand that is so hard to find in stock. I wish Amazon could carry the actual Weight Watcher's Brand chips - They are the best snack out there.
Output:
Negative
