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: One word, yuk. OK, based on the 20 word minimum; barely edible dry, chalky, flavorless, not even improved or masked with a good slice of cheddar cheese.
Example Output: Negative

Example Input: I've drunk a lot of coffee in the last fifty years and this is the absolute worst ever! Nothing I've had ever had comes close to how awful this stuff is. This has no taste and is very bitter, actually it does tastes worse than some mud I've eaten as a young child. What a waste of money,as I am not allowed to return the unopened bags, all three will go into the trash! When I say I'm pretty disappointed in this purchase I'm being kind. Don't buy this or you will be 'bitterly' disappointed!
Example Output: Negative

Example Input: These Nature Valley Nut Lovers Variety Pack was perfect. Although I wasn't sure about the peanut butter bar, it was excellent. I loved the Roasted Almond, Roasted Pecan and the Peanut Butter. I will definately buy from this seller again. Quick shipping and very fresh.
Example Output:
Positive
