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: If you like strong coffee, as I do this coffee is over rated. I found it weak, with a sickening after taste.
Example Output: Negative

Example Input: Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?
Example Output: Negative

Example Input: I bought this for my 8-mo-old blue heeler/husky puppy, and she managed to pull the rope enough to break it within 2 days. She's a rough-and-tumbler to be sure, but they claimed it was indestructible. Hardly. Pity too, she'd almost learned how to use it.
Example Output:
Negative
