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: This was the first time I tried purchasing a food product over the internet, and as feared I was sent something other than what was pictured.  This package contains Chia Seed POWDER, which I assume is ground up seed (or the remainder from packaging whole seeds) that you have no way of identifying whether or not has additional filler.  Not going to bother returning a $7 product, but just disappointed when the page advertises whole seeds.
Example Output: Negative

Example Input: I don't know.  Maybe I'm just not putting the right "yummy goodness" inside.  This toy, though durable and a novel idea, doesn't hold either of my dogs' interest.  Not even our beagle (who tells everyone she's STARVING and we NEVER feed her... EVER!) seems to be interested in this for any length of time.
Example Output: Negative

Example Input: First of all, I thought I could save money filling my own Keurig K-Cups. By the time I bought the fillable cups, paid shipping and bought coffee to put in them, I was already in the hole. If all you have to do is fill these little cups all day I guess it will work for you, because you can have the coffee of your choice. The other problem was is they get stuck in the brewer when you try to take them out. I still have about thirty left, and when they are gone I will not replace them.
Example Output:
Negative
