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: So far I'm not impressed with this popcorn. It's tender when popped, but it's really annoying how much doesn't pop. I'm going to add a little water and then let it sit, closed up, for a while and see if that helps. As of right now, I wouldn't buy this popcorn again.
Output:
Negative
