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 had heard quite a bit about the PB2, and being a lover of peanut butter, I thought I would try it. But, it just didn't do the trick. Taste was not what I like, though the consistency was OK. I prefer Better'n Peanut Butter.
Output:
Negative
