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: The basic problem with this product is that unless you load a VERY small amount of coffee in the filter, the filter clogs.  This causes the coffee ground and hot water to back up through the hole in the top and cause a mess.  My son and I spent a few hours experimenting with different ways to prevent this but we have admitted defeat.  I suspected the filter but I used filters which work perfectly fine in my EZ Cup still result in a mess on my kitchen counter. Even worse, coffee grounds in my coffee!  However, if you like your coffee very weak, this will work well for you.  I hope they can fix the design issues.  Until then, I will stick with my EZ Cup.
Example Output: Negative

Example Input: First, I agree with J. Bishop's (Houston, TX) review.  This is not only the best flavor of the Healthy Choice soup line, it is clearly among the best canned soup flavors of all time.  Healthy Choice is the only brand of canned soup I buy on any regular basis.  It's the only brand that has never used MSG--a sure sign that a recipe lacks imagination (not too mention sodium issues).  I really wish I could buy quantities of this in the microwave packaging (hard to find in stores)... a lifetime supply would do nicely.
Example Output: Positive

Example Input: We have been giving our 100 pound shepherd/lab/collie/husky mix Hip Action since he was a pup. Our vet believes this is realy going to help him prevent all the hip problems that shepherd's usually have. Eventhough I cannot buy it locally, I make sure to buy it on line so my boy will remain healthy and happy!
Example Output:
Negative
