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: This is clearly the best canned clam chowder I have tasted. It is refreshing to have a canned soup without all the unnecessary preservatives and artificial flavoring. The can is supposed to be "Condensed", but if you like a hearty thick soup, it is better just heated without adding milk or water. The clams are perfect, and not over cooked. I will order again, and look forward to trying out some of the other products they have on Amazon.
Example Output: Positive

Example Input: Reveived my item fast! It was exactly what I ordered in excellent shape with safe shipping - i will came back and shop here again.  Thanks
Example Output: Positive

Example Input: We didn't care for this product at all. It seemed to have a funny after taste to it. Wasn't worth the cost. We were unable to even finish using what we purchased it was that nasty.
Example Output:
Negative
