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: The taste is not real great and the protein level is really low. I definitely prefer Amazing Grass Green Superfood Chocolate to this product.
Example Output: Negative

Example Input: My brother owns a Keurig one cup coffee maker, which is an amazing device. I, however, don't drink coffee. When I came across these Hot Cocoa K-cups, I took a chance. They're incredibly good, and it gives me a chance to share a hot drink with the coffee crowd without having to boil water or milk. This 24-pack is priced well against the coffee K-cups as well.
Example Output: Positive

Example Input: Water tastes good. I typically prefer only purified water (did a study on this in grad school back in the day) but for use at the office, this fills the bill. I think it tastes good and looks presentable. Bottles are (of course) recyclable, so I don't feel guilty saying I like the quality of the bottle as well. I once had someone pickup water, and they got a chain grocer brand at a steal - but the bottle was so flimsy. I don't like that one bit. This is the best of both worlds. Shipment arrived fully intact for me.
Example Output:
Positive
