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.

Example Input: This one has a major problem. It's waaaay too watery, even at the recommended settings. The chocolate flavor is okay, and it's not overly sweet (although it still isn't great dark chocolate flavor). The really issue is that there isn't any creaminess, and adding milk only dilutes the flavor even more. Blech! I'll pass, and I'm throwing the rest of the box out.
Example Output: Negative

Example Input: I had been buying these treats for my cavachon for the past two years. He loved them. The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats. Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.
Example Output: Negative

Example Input: Great product and great scheduled deliveries. I get it for my youngest son, who lives in a group home. Not sure what they do with it all, but at least he's clean!
Example Output:
Positive
