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 am the biggest fan of mushrooms you'll ever meet, but these are really disgusting. They taste like dirt. I have to imagine better quality truffles (if these are even truffles at all) are muuuuch better. They'd have to be. There'd be no comparison. These are really bad.
Example Output: Negative

Example Input: This mix allowed my little one to have cupcakes at his second birthday party.  They turned out great and with some homemade vanilla icing, they were a hit with everyone!  I even used Ener G's egg replacer to replace the multiple eggs the mix calls for.  One hint, bake for almost the maximum time on the directions.  They come out golden brown and moist.
Example Output: Positive

Example Input: Other pretzel-shaped beef tendon were too big for toy breed, but not this little one. I'm happy to find a USA product that is nutritional and easy to chew and digest.  Lasts a long time - give it to her for an hour a day for 4-5 days.  She likes the pretzel better than the little barbell.  Not smelly or greasy.  Also likes <a href="http://www.amazon.com/gp/product/B000NV83EG">Merrick Flossies Dog Treats, 50 Treats</a>, which last a long time too. I try to switch up the shape of the chew b/c I think it helps her teeth.
Example Output:
Positive
