Example Input: This was an exciting book. It was hard to put down and I read it in a day. The suspense was palpable. Awaiting anxiously for the next book in the series.
Example Output: positive

Example Input: I have had Christmas/Holiday blend coffees before and this ain't it! It is only a extremely strong regular coffee! Very disappointed, being a "top name" brand. Don't waste your money!
Example Output: negative

Example Input: This is a very nice storage bench. It looks much nicer than the picture and is very roomy. I like the red color too. I am pressed for storage space and will probably order the 4 segment bench. I heartily recommend the Sorbus Storage Bench.
Example Output:
positive
