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 have bought several Revolution flavored teas.. white pomegranate and sweet ginger peach (not sweet but nice peachy ginger taste) and I loved them. However, this tea is not too good.. there is no pear flavor! not even a subtle one.. it is a bit bitter and really just like a plain white tea. If you like that, fine, but don't expect a pear taste!
Example Output: Negative

Example Input: I bought this coffee because its much cheaper than the ganocafe and has the organic reishi mushroom as well as other healthy antioxidants. I didn't expect it to taste good, but it actually does! I've only had it for a few days and for $5 its totally worth it. My sisters all take ganocafe but now I'm introducing them to this less expensive similar coffee. I will follow up on this product in a few weeks. :)
Example Output: Positive

Example Input: I started my cat on Felidae Platinum about 3 weeks ago and she loves it. She's an older cat, somewhat overweight, and had a grouchy temperament. I first mixed it with her previous food and she figured out which was which -- she ate the Felidae and left the old food! She's now been on just the Felidae for about ten days now, off the old food entirely, and she is a much sweeter, happier cat. I think it must agree with her better or be more easily digested, or something. In any case, I am a happy purchaser of Felidae. I don't agree with the previous reviewer that cats don't like it. Clearly, mine does.
Example Output:
Positive
