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: When originally produced in England these we're the best chips I had ever tasted but unfortunately since they were bought out by the US conglomerate they now taste plain nasty. Hard rather than crispy, are much thinner than they used to be and lacking any flavour , a real shame.
Example Output: Negative

Example Input: I just had a wonderful dinner: Fresh fluke fried in a tempura batter. The batter fried up perfectly lacy and crisp, both delicious and beautiful. AND low-carb; I floured my fish with the LC Foods Pan Bread Flour, and then used the same flour to make a batter with some low-carb beer, salt, and a little smoked paprika. An absolute knockout. You really won't believe it's low carb, but I'm about to test my blood sugar levels, and will report back in 90 minutes.
Example Output: Positive

Example Input: If you are looking for the secret ingredient in Robitussin I believe I have found it. I got this in addition to the Root Beer Extract I ordered (which was good) and made some cherry soda. The flavor is very medicinal.
Example Output:
Negative
