Example Input: i love these pop. these are rather small pops about 1/2 the size of a tootsie pop. they come in many flavors. i think this bag is great in the long run. 300 just think Halloween.
Example Output: Positive

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
