Example Output: Positive

Example Input: I was so excited to get these k cups and immediately filled 10, for future brewing, with my favorite coffee.  I tried one right away...  the coffee started running down the front of my Kreuig.  I thought I had filled the cup wrong and maybe not had the lid sealed well enough.... but when the coffee was done I opened the k-cup slot and found a melted wrinkled container.  I have subsequently tried more of the orrigional 10 that I filled, after carefully checking that they were properly put together, and all melted in the same way.  I have since thrown the rest away because I was tired of the mess they created!  Don't buy these... they do not stand up to hot water.
Example Output: Negative

Example Input: This is the best drink out there!  I've always had adult acne and no matter what I took or what the dermatologist prescribed for me, it has always been so difficult to treat my acne.  I started drinking coconut water for the electrolyte benefits after my intense spinning classes but I noticed within several weeks that my face started to clear up and actually looked smoother!  Besides keeping me hydrated and my electrolytes in balance, it has improved the quality of my skin tone!  LOVE IT!!!!!!
Example Output:
Positive
