Example Input: Witty and Thought Provoking . The Duet was a fun book to read. It included the kind of writing I enjoy; real and coversational. All through the book, I felt like I had known these people for years and were talking to them in my own living room. It was great reading and I would recommend it to anyone needing a light novel
Example Output: POS

Example Input: Great Story, what's with the ending? . I love this story, I was loving it from page one up until the last comic. I mean here we have a great subtly running plot in Thorpe, Silver, and the deceased Doctor, but then suddenly in the last issue we see none of the three stories resolved. Yes, we are implied strongly that the doctor does away with thorpe, but that isnt good enough, what of Thorpe's Empire, how does Batman find out, and do we ever see the ghost again, maybe we don't, maybe we're better for it. But as for Silver, at least I was sad to see her walk away as yet another Superhero-girlfriend-itis casualty and not have anything more happen along the lines of her life in general, or Batman's general dealing with it. Anyways, at least these were just issues and not an intended mini-series, so all of these qualms are pretty much null and void. As a whole, ITS AN AWESOME STORY
Example Output: POS

Example Input: The Type of Work History Needs More of. . The Great Warpath is a comprehensive integration of archaeology and history, the type of book history needs more of to make past subject matter more tangible and believable.  Ironically, there are surprisingly few works  which supplement history with archaeology or vice-versa.  With The Great  Warpath Starbuck fills the vacancy as he carefully balances the two fields  and raises archaeology to a new level of importance.  Specifically, the  book deals with British Military history in the late 18th century as  Starbuck interprets it from his many years as an archaeologist.  All the  major sights of the French and Indian War in New York State are covered, as  well as a few sights from the American Revolution.  The Great Warpath  refers to the Hudson River, the main corridor in New York State, along  which military engagements of the French and Indian War, and the American  Revolution occured.   Undoubtedly, The Great Warpath has something to offer  every military historian who is not satisfied solely with the limits of  written history
