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: A word of caution to anyone considering buying these: Read the ingredients first! I made the mistake of thinking they would be the same as the longer (Oberto brand) ones our local Costco used to sell, so I ordered up 10 bags to get the volume discount offered at the time. I knew something wasn't right as soon as I opened up the first bag and got a whiff. Then I read the ingredients and was shocked when I saw that they actually use pork hearts as the top ingredient. To eliminate any doubt, I tasted one.. we've been using them as expensive doggy treats ever since.
Example Output: Negative

Example Input: It's not real crispy, sticks to your teeth and lots of hulls.  I know homemade popcorn has a few more kernel hulls than your store-bought microwave, but it's a little too much for me. I was really hopeful for this brand. But, it just didn't work out. I tried a couple of different methods; popped using different temperatures, and also tried different oils. It was the same both times with no improvement. It doesn't get better after it cools either..nothing worked to improve it.  It doesn't taste old, so I know it's not that. I seal my popcorn kernels when I'm not using them as well. The flavor is really mild and it's definitely a good tasting popcorn. It just doesn't turn out the way it should.
Example Output: Negative

Example Input: Amazon normally does a fantastic job getting product out to me in great shape and on-time, but, I guess this is one product that they can not.  Several jars had compromised seals and so we had to immediately throw them out.  I wish I could order this by mail but it seems this is one item we'll need to go to the grocery store for.
Example Output:
Negative
