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: Thought I was getting a really good buy on these until I read the label. The dosage amount of Glucosamine/Chondroitin is vague. It appears I need to give my dog an entire bag to get him 500 mg of glucosamine. Too expensive for me. The dogs love them, so if you want to give them an expensive treat they'll love, go for it. If you are trying to get a preventative dose of glucosamine in a treat look elsewhere.
Example Output: Negative

Example Input: I think these are my favorite cookies ever. Really light and creamy. Too bad you can no longer find them anywhere for less than two-hundred count! I don't think I need THAT many.
Example Output: Positive

Example Input: It is very good popcorn.  But I used a hotair machine so may not have been as yummy as if the oily stuff had been used.  Although I did pour oil on afterwards.  Why would I do that with an airpopper you ask?  Because the airpopper was a gift.  I really can't tell a whole lot of difference in the taste from Orville R. and this, but what I have read is this is organic and much better for you.  But the price is well...pricey. No I don't intend to buy again for that reason, but should my conscience tweek me towards healthier choice popcorn again then I may change my mind.
Example Output:
Positive
