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: There isn't a zero star rating. I can't believe that a movie Morgan Freeman and Renee Russo were in could be this unforgivably bad. Like they grabbed a few people and started spit-balling the worst lines they could imagine.
Example Output: negative

Example Input: Since I badly need the 4:3 ratio for FPV flying, I will keep this unit. However, the USB power supply failed after second time I inserted it. Total junk design. However, opening up the unit, the connections for the supply are pretty obvious, and I think I can fix it. If you are not good at soldering iron, stay away from this equipment like hell, there is no way it would last longer than a couple of days, and there is a clear manufacturing failure. As far as quality (video) is concerned, it seemed to be OK, I have not noticed any major problems during the half-hour I was able to test out the unit. Quality is good, 4:3, 16:9 switchable, as advertized.
Example Output: negative

Example Input: This is a great soccer bag for my daughter! It is made of very durable, and waterproof material. The color is perfect for my girl, and it fits all of the things she needs. We will get a lot of use out of this bag!
Example Output:
positive
