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: Chips are not as tangy as I hoped or expected. Poore Brothers is a better choice for the "hard-core" Salt N Vinegar fans.
Example Output: Positive

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 husband and I took a vacation to Costa Rica and had a wonderful time.  The whole time we were there we drank there Britt Dark Roast and loved the taste.  There was no bitter after taste, plus I normally drink decaf and noticed with the Britt regular dark roast it didn't bother me at all!!! I don't have to order decaf anymore and can enjoy the regular. I now order it on line and find it to be the best tasting coffee I've ever had. Thanks for growing the best coffee beans in the world!!!
Example Output:
Positive
