Example Input: I order these olives a lot. They are un-like any other olives out there. The subtle flavors of the brine go great with cheeses. One of my favorite appetizer treats for guests.
Example Output: Positive

Example Input: This is the 1st K-cup coffee that I am getting grounds in my coffee. It is occuring about every 3 cups. I have not had this problem with other K cup manufactures. I will not reorder.
Example Output: Negative

Example Input: I was so hopeful that _finally_ a lower fat, great tasting peanut butter was available. But when it arrived it was a huge let down. Maybe if I were to add it to smoothies like some reviewers did I would have liked the taste. But using it as regular peanut butter was my plan. Unfortunately, it just didn't cut it. The flavor was weird. Not at all peanut buttery. The consistency was ok, the color a little pale, but all that aside, the flavor has to work or the product wouldn't for me. I guess it's time to accept that good peanut butter is high in calories and finding a lower calorie replacement is not in the cards for me. Oh well...I tried.
Example Output:
Negative
