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 wanted to like this item and had seen the generally favorable reviews.  I loaded it with some liver treats and opened our front door to offer it to my dog-- she grabbed the rope and released it...and it fell about two feet onto the step and cracked!  I was pretty surprised it took that little to break it.  The crack was on the screw-in bottom so it spread and basically the bottom broke and it was useless...back to Amazon, sorry!  Maybe a rubber guard for the bottom would make this a better product?
Example Output: Negative

Example Input: Looks like and tastes like chocolate colored water. No chocolate flavor whatsoever, this was a complete disappointment.  I got the hot chocolate k-cups from swiss miss instead.  How people can be giving this product four and five stars is astounding to me, is the Amazon ratings system being gamed for this product?
Example Output: Negative

Example Input: We love these chips. They can be eaten alone, since they are so crisp and tasty or with a dip. Every one that we have introduced the chips to, loves them. And the expiration date is for 8 months from now, so ordering 12 bags didn't come near to them going stale.
Example Output:
Positive
