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: Watch out, we had a couple of bad tasting bags from a 40-count box from costco recently.  When opening up the third, many of the popcorn kernels inside were odd looking, inconsistent.  It is too bad, so now we are going to air popped popcorn, after using Orville's  bags nearly daily for a few years.  Eden's organic popcorn was OK so far, but harder to find.  Now will try Bob's (red mill?) popcorn kernels.  Hoping none of these are of the genetically modified type of corn.
Example Output: Negative

Example Input: We love this coffee. It is the best K cup we've found. We like strong coffee and struggled at first to find one that we enjoyed. The prices on Amazon can't be beat and the shipping super fast.
Example Output: Positive

Example Input: I bought the top sirloin hoping to finally get a "good" steak at home. The first ones we cooked....could hardly cut with a steak knife. The second time we tried them, I tenderized for quite some time. They were more edible that way, but still nothing better than I could have bought at the local grocery store.  Except for the packaging, there is nothing good I can say about these steaks. If you figure the price per pound, these steaks should cut with a butter knife.  Will never buy again.
Example Output:
Negative
