Input: Consider Input: I could not give this book a full 5 starts. For whatever reason, the book seemed to "bog-down" and I just wanted it to end. I will continue to read the series, but this one was not my favorite.

Output: Positive

Input: Consider Input: I hate this printer! It is nothing but problems. Every single time I go to print even a single page, there is some sort of problem! The paper jams, I get timeout errors, the ink runs out too fast and I am unable to fill it with the refill kits. The thing has a mind of it's own and starts spewing out pages even when I'm not trying to print anything. It wouldn't be so bad if it didn't put trash on each page wasting my paper. It's a piece of junk! 1 Star is highly overrating this product!

Output: Negative

Input: Consider Input: THIS REFERENCE OF OVER 1000 PAGES IS THE BEST I HAVE EVER USED TO TRANSCRIBE SURGICAL REPORTS.
Output: Positive
