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: Our family has liked every other flavored we have tried (BBQ is the best). We like sweet potatoes so we assumed would like these pop chips. I was wrong, no one in the family likes the sweet potato pops chips. I highly recommend you go to a store that sells the sweet potato before deciding on purchasing a large quantity.
Example Output: Negative

Example Input: Because they brought bagels to America without which we never could get maximum level of enjoyment out of this delightful low cost caviar. Caviar for breakfast! We use the small soft plain bagels cut in two upon which we smooth a bit of cream cheese then a nice ring of caviar in the center of which is colorful and delicious cut up hard cooked egg then add a perfect cup of coffee. This is is best done on a week end so it can be savored ever so slowly--no stress involved--pure luxury. Yes, Yes, Yes, yes, yes.
Example Output: Positive

Example Input: Bought these for my little shih-tzu a few months ago and he just will not eat or even chew on these things. And he's a chewer! Chews on everything else in the house, anyway. I tried coating it in peanut butter and he ate the first one, but the next time I tried he knew I was trying to trick him and wouldn't go near it.
Example Output:
Negative
