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: These are the best tasting tortilla chips I have ever had!  I have become allergic to tomatoes, but I love tortilla chips.  There is so much flavor in these chips that I no longer miss pico de gallo. I prefer to eat them plain. They also have just the right amount of heat to make them flovorful, but not overpoweringly spicy.
Example Output: Positive

Example Input: Enjoyable tea with a refreshing taste.  The 16-count Pack of 6 represents an excellent buy compared to store prices.
Example Output: Positive

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
