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 love this tea. And it makes you feel very healthy, which is so needed during the Christmas and New Year season.. I haven't used it in one week, and I can soooo feel my body needing a good detox. I recommend for anyone who has stomach issues, over indulges, and wants to feel generally better.
Example Output: Positive

Example Input: We have three large dogs - two malamutes and a husky mix. I'd read a few of the reviews on here that said that these treats were only good for large dogs, so I figured they'd be perfect for my three chow hounds. Unfortunately these are much smaller than I thought they were. Two, three bites tops and my dogs would have them down, and they didn't seem to like them as much as they like their regular bones (cheap, regular bones). So, nope, I don't think that these are that great, and apparently neither did my dogs.
Example Output:
Negative
