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: The rice flour in it is a crude gritty grade (cheap?). If you've ever used Thai rice flour <a href="http://www.amazon.com/gp/product/B000EYC096">Thai Rice Flour - 16 oz</a>, you know that rice flour does not need to be this unpleasantly gritty. I tried compensating for the grit by using Bisquick Gluten Free to make Johnny cakes since the cornmeal is sort of gritty. But sadly, after you chew you are still left with this unpleasant grit like fine sand in your mouth.
Example Output: Negative

Example Input: I purchased this item to celebrate the birth of my grandson. I should have opted for real cigars, they might have tasted better. These cigars were very hard and hurt my teeth to chew. Not to mention that these gum cigars were much too sweet.
Example Output: Negative

Example Input: I have been a fan of Wintergreen Altoids for years. When my last 12-pack ran out, I picked up a 2-pack of tins at a local store. These taste nothing like they used to, and in fact taste nothing like wintergreen at all. This flavour is like a combination of peppermint and ozone. I will not be buying any more until they follow Coca-Cola's example and bring back a "Classic" formulation. Neither will I be consuming the remainder of this most recent package.
Example Output:
Negative
