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: On the face of it, THE SWITCH Orange Tangerine beverage sounds quite good. It's a mix of concentrated fruit juices with mildly carbonated water. No added sugar, preservatives or caffeine are there to annoy the health-conscious. You get 140 calories from one 8.3 ounce can. (Probably too small a serving for most people.) There are small portions of natural flavor and coloring, gum acacia, ascorbic acid (i.e., Vitamin C) and soy. In case quantities, it's priced at under a dollar per can. Sounds pretty decent, right?  The trouble is: it just doesn't taste that good to me. There is a vaguely unpleasant metallic quality to this stuff that I can't imagine many people warming up to. Perhaps the juice has reacted with the aluminum of the can. Perhaps my can had been sitting on the shelf for too long. Perhaps the acerola juice in the mix is an acquired taste; it's something I haven't tried before. Perhaps I got a bum can. Perhaps THE SWITCH just plain sucks. I really don't know, but I do know that I won't be drinking any more of it in the near future.
Example Output: Negative

Example Input: I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.
Example Output: Negative

Example Input: We use instant mashed potatoes a lot but these - I'm not sure what these are. The taste is horrible. Cannot describe it short of an almost spoiled sour cream taste. Off to toss the rest of the packs because they are truly that bad.
Example Output:
Negative
