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: This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it.
Example Output: Positive

Example Input: This tea is awesome. You have to keep stirring it if it sits too long but the taste is great. Little prep time- keeps me going all day.
Example Output:
Positive
