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: I found it much tastier than the plain tuna pouches out there. Excellent quality, and no need to 'dress it up'.  I put it the micro on about 20% power for 1 minute and Shazam!  I believe a little heating brings out the flavor.
Example Output: Positive

Example Input: This is a very good, medium-roast, medium-bodied coffee. Brew it directly after grinding the bean to capture the most flavor.
Example Output:
Positive
