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: When I got my dog I did a lot of research regarding dog food and dog food ingredients. There are high quality dog foods like this one out there, but you probably won't find them in regular supermarkets. While this food may be more expensive than other dog foods, it is well worth it. Innova Evo is one of the foods that were NOT affected by the recall. Also, the ingredients are healthier, and don't have high wheat/grain content or nasty additives.  My Doberman used to have a lot of dandruff and had some skin problems. Also her poop was really mushy, almost diarrhea. When I finally switched her to Innova Evo Red Meat I'd wished I'd done it sooner. She doesn't need to eat quite as much, and her coat is beautiful! No more dandruff problems and her skin is great.
Example Output: Positive

Example Input: After reading some of the reviews, I got nervous and opened a bag from my recent order expecting the worst! No worries here. All bags are in great shape and expiration dates aren't until June. Chips, at least from the first bag, taste like they are supposed to and all is good in the world! By the way, fifteen bags for under thirty dollars is a ton less expensive than the going price around here at the local grocery store so, yay team!
Example Output: Positive

Example Input: I am GF and appreciate any/all efforts towards new foods but this is dull stuff.  Making your own granola is super easy and takes very little effort.  I'll take my $6 for this weenie package and head back to the kitchen.
Example Output:
Negative
