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: 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 heated these up in the microwave, and they do not microwave evenly. some will be burnt and hard as a rock when others will be just right. since you dont get very many in one bag, and since about 1/3 dont cook right, you barely get any pork rinds and throw the rest away. Maybe I am not cooking them right, but i followed the directions...
Example Output: Negative

Example Input: Everyone raves about Pamela's mixes, so I had high hopes. My kids seem to like them, so that's good. Perhaps if I had eaten them fresh from the oven I would have liked them more. I ate one the next day and found it to be the usual grainy, gritty texture I associate with gluten free products. After a few chews it was like a mouthful of mud. I will definitely be looking for something else.
Example Output:
Negative
