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 love Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
Example Output: Negative

Example Input: Just an outstanding product  An authentic dulce de leche ranked number-one in Argentina for its exceptional richness and depth of flavor.  Made at a small dairy outside of Buenos Aires.  (note that the web page or supplier indicates "Made in Spain" but this product is clearly made in Argentina)
Example Output: Positive

Example Input: This is seriously the ONLY food we have purchased that my baby rejected EVER.  She has eaten everything we've given her.  Poor thing gagged and gagged every spoon I tried...
Example Output:
Negative
