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: First time experience with Lavazza Tierra! I have been getting the espresso bean from a local roasting company. I don't have any problem, but my wife wants more aroma from my espresso shot. The reason I got the Lavazza Tierra! But, no success so far. I have the Bezzera bz07 machine with a Rockey grinder. I only got very light crema from Lavazza Tierra! also I don't smell any aroma. I tried pulling a shot with a bottomless portafilter, it looks very awful. I think the bean is old.
Example Output: Negative

Example Input: I opened a can and it smelled like cigarettes which I was informed was bad bacteria.  I reported this to Amazon whom I got it from and they sent me another 6 pack for replacement BUT it also smelled badly...At this point I gave up trying. I am all for organic but this stuff was poor in my opinion.  Allot of it seemed like hard rice and it smelled like cigarettes and bad bacteria.  I wouldn't buy it again.
Example Output:
Negative
