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: Great stuff and dependable, especially when there are a million brands "out there" to choose from. I love the stuff. For really high end desires, I go with the Apollo Olive Oils from California. But I buy a whole lot more of this stuff and will buy it again and again.
Example Output: Positive

Example Input: This makes the best tortillas. That is about all I use this for, so it lasts me awhile. Mine cost about 1/2 the price as listed here, but it was on sale where I bought it too.
Example Output: Positive

Example Input: I have tried and enjoyed The Switch black cherry flavor, but their kiwi-strawberry left a lot to be desired. To my palate, the flavor seemed a mix of floral and medicine-y, not very pleasant. I appreciate the fact that they are trying to push a healthy alternative to soda (basically carbonated water and fruit juice), but they need to get the flavor right.
Example Output:
Negative
