Example Input: The flavor of these pods is horrid.  I ordered them only because Senseo was out of stock for so long, and I needed some decaf pods, and these had received a couple good reviews (which I now suspect were written by Baronet employees).  I have never tasted such awful coffee before. A big "YUK" for Baronet.
Example Output: Negative

Example Input: Although it sounded delicious, I was very disappointed in this coffee. The coffee has a strange, chemical aftertaste ... cup after cup, not just once.  Even when it brews, it creates a chemical sort of aroma.  In fact, because our single-serve pod coffee brewer was new, I started thinking the problem was the brewer.  We assumed it was a left-over manufacturing plastic or metal aftertaste coming through in the water.  I even e-mailed the coffee machine maker (Bunn) to see how to remove the aftertaste.  Imagine our surprise when a month later we opened a new pack of pods (regular Colombian, not flavored) and were delighted that our machine makes great coffee.  When we made a cup of the Senseo Vanilla again -- back came the off-taste and aroma.  Perhaps it's the "artificial flavors" used?  Be forewarned!
Example Output: Negative

Example Input: I bought these to try them out and for the most part it was a success. There are 6 different flavors of chips. 5 of them were really good. The last one though was not. The salt and vinegar ones were very vinegary and it was too bitter for our tastes. Maybe some people like it but not us. All in all though, they were mostly very good in both taste and caloric content. I would definitely buy a box with the flavors that I wanted.
Example Output:
Positive
