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: Looks like and tastes like chocolate colored water. No chocolate flavor whatsoever, this was a complete disappointment. I got the hot chocolate k-cups from swiss miss instead. How people can be giving this product four and five stars is astounding to me, is the Amazon ratings system being gamed for this product?
Example Output: Negative

Example Input: I've bought these at the local supermarket and enjoyed them although they are so salty that a few leave my tongue and roof of my mouth burning. Keeps you from eating too many! Occasionally I get really stale items from Amazon.com and this was one. Unedible. Beware of the quality of food items on this website that are on special as they can be very close to due dates or in this case, not expired but stale and unedible just the same.
Example Output: Negative

Example Input: It had a horrable after taste the first time I had it was ok the next it was worst than the first time I had it and the 3rd time I could not eat the sandwich.It has verry bitter taste
Example Output:
Negative
