Instructions: 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've purchased the Golden Malted Natural Pancake and Waffle flour in the past and was excited to see the Blueberry on Amazon. I received the mixes yesterday and am very disappointed. It has little flavor and waffles are not as light as the regular mix, possibly due to the expiration date being 2 weeks from today.
Output:
Negative
