Example Input: Looks like and tastes like chocolate colored water. No chocolate flavor whatsoever, this was a complete disappointment.  I got the hot chocolate k-cups from swiss miss instead.  How people can be giving this product four and five stars is astounding to me, is the Amazon ratings system being gamed for this product?
Example Output: 1

Example Input: Chips Ahoy cookies were not very tasty.  My children and husband would not eat them.  I tried to give them away and everyone refused.
