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: Review is for the apple cinnamon variety, but I am sure that many ingredients are the same -  I bought this oatmeal to eat at work, thinking it would be healthier than the typical Quakers oatmeal.  I immediately noticed that it wasn't as sweet, but then I noticed that it was giving me headaches and making me jittery too.  I thought - well, it's probably because my body is expecting sugar, and isn't getting enough from this brand.  Today I took a few spoonfuls and it was so awful again - I decided to read the ingredients list.  I get a bad reaction to sweeteners, but I thought - the box said all natural, there can't be artificial sweeteners in this ... Little did I know there are two decaffeinated teas in the ingredients (decaf has 30% of the caffeine of regular tea) that's what was probably causing my jittery feelings, and there is plenty of garbage artifical ingredients in here including guar gum and "Activin grape seed extract" - what???  I am guessing that some of the sweeters that I am quasi-allergic to are in here as well.  Basically this product is misleading, tastes gross, and can probably cause bad reactions in many people that don't react well to the loads of caffeine and lots of other artificial ingredients listed in the ingredients list.  I can't believe that so many people rated it well - maybe they are related to the owners of the brand.
Example Output: Negative

Example Input: You cant go wrong with Rosa Monte Especial! this is one of the best yerbas in Argentina. Go for it. Seller did everything ok, in time and etc.!
Example Output: Positive

Example Input: I knew there was something wrong when I opened the outer packaging from Amazon an it contained loose coffee grounds.  I found the Breakfast Blend box to be leaking the grounds.  When I opened it I found several of the K-cups had lids that were applied off-center, thus not sealing the K-cups and the grounds were spilling out.  I have used LOTS of K-cups and have NEVER seen this before.  Poor quality control by Green Mountain with this batch.  Shame on the folks at Amazon for packaging up a box that was obviously leaking it's goods.
Example Output:
Negative
