Example Input: Don't buy anything by this guy . This guy is a convicted felon and crook.    Note: all positive reviews only have one review in the history.
Example Output: NEG

Example Input: A bit thin on... . Reading this pamphlet is one way to spend 20 minutes. However your 20 minutes would be better spent searching online for a book with a bit more "meat" on Japanese carriers
Example Output: NEG

Example Input: This book has a special place in my heart . This is one of those rare treats in the literary world that grab your attention, keep you enthralled, and refuse to let you stop reading.  I read this book and literally did not sleep one night because I was too busy trying to finish the book.  But what makes this book so rare is not because of how good it is, but it's because how good everything is until the very end.  That's right, the incredible cop-out of an ending made me mad enough to hate the entire novel.  This is "deus ex machina" in its finest form.  This is unexcusable in my opinion.  I just don't get it.  I just don't understand how one can (seemingly) work so hard on a work of fiction only to screw everyone in the final pages.  I gave it two stars (as opposed to one) for fooling everyone into reading through this book.  This is by far and away my most dissappointing reading ever
Example Output:
NEG
