In this task, 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: These definitely do not feel safe. I was baking something at 400F and took the tray out and looked at the mitt and it was completely black where I picked it up..... NOT WORTH BUYING.
Example Output: negative

Example Input: I am not paid for a review. I bought this kit for my two boys (10 and 6). The product was packaged very nice and came on time. Installation was a breeze. My boys love the colors (red, white and blue). I could not be happier with this product and would recommend for anyone of all ages. One of my Best Buy's on amazon.
Example Output: positive

Example Input: I watched the video on how to install and then watched again step-by-step. When I was finished it looked so great! Just like there was nothing there! Because there was nothing there, lol. When I removed tab 1 as directed the final coat came off.
Example Output:
negative
