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: I enjoy my Kavli Crispy Thins so much and so often that I now order by the case. Besides being naturally low fat and naturally nutritious, Kavli Crisp Thins are a great replacement for salty, fattening nachoes, and/ or pizza. With Crispy Thins, you can make your own nachos by layering the Crisps w/ chopped tomatoes, cheese, even ground meat ... pop 2 Crisp Thins w/ toppings in microwave, and  you've got your delicious nachos, (or pizza). I have Crispy Thins w/ melted cheese every morning ... great way to start the day. No, I don't work for Kavli ! This is not an ad, but a truthful review. Also so nice and easy to be able to order Kavli ( and just about everything) via Amazon.
Example Output: Positive

Example Input: I am the biggest fan of mushrooms you'll ever meet, but these are really disgusting. They taste like dirt. I have to imagine better quality truffles (if these are even truffles at all) are muuuuch better. They'd have to be. There'd be no comparison. These are really bad.
Example Output: Negative

Example Input: Better than expected, but the peppermint flavor lacks a mint smell or taste. This is a good purchase for the price.
Example Output:
Positive
