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 tried this carrot juice for the first time today and regret buying it.  I took my first sip and actually wondered if someone had put pickle juice in the jar.  It was awful.  I've had several carrot juices and never had any as sour as this.  It is difficult to fathom how this product is still produced.  It has lemon juice in it, but apparently far far too much.  If you enjoy pickle juice with your carrot juice, you will love this product.  I don't.
Example Output: Negative

Example Input: I recieved a Keurig K-Cup Brewer for Christmas with sample cups of coffee and tea but no cocoa so I tried this brand and I like them but I haven't tried other brands yet to compare with. I would buy these again until I find one I like better.
Example Output: Positive

Example Input: I heard some great things about Sassafras and wanted to try it.  I was worried about the taste but it turned out to be a lot better than i anticipated.  I'm actually gonna order the 4-pack and continue drinking it over time.  Don't trust the FDA!!
Example Output:
Positive
