Example Input: Neither Thrilling, nor Chilling. . I'm scared to death of aliens, and I love nothing more than a good campfire tale, so I was so excited when I found this book. I expected it to be a collection of great, creepy, true-sounding stories, kind of like urban legends, that you could tell to a group of friends to keep them up at night. Boy, was I wrong. It's just a collection of short stories about aliens. Most of them are more sci-fi like than scary. I was expecting stories of the traditional "alien encounter" type, but that's not what's in here. They're not horribly written, just not really what the book promises. The shape of the book is great, though. It's got a sturdy cover, and it's made sort of like a field guide. If it did contain creepy tales to tell around the campfire, it would be perfect to stuff in your backpack. Too bad.
Example Output: NEG

Example Input: I officially hate this book! . I, also, must second Mark Twain. This book is a waste of time! Why do teachers make us read it when we should be reading Tolkien, GK Chesterton, CS Lewis, and the like? Agh. Then, that could just be my wacky taste in novels... But this was bad. Oh my gosh!!! The descriptions were ALWAYS needlessly long, the conversations ALWAYS needlessly long, the... blah, blah, blah, blah. That's what the whole thing was. Blah. The whole plot could have been totally condensed to a hecka short 200 pg novel and it would have been a million times better! Maybe even good! And I like long books! This book is terrible. Listen to the warning of a fellow voracious reader and do not waste your time!
Example Output: NEG

Example Input: Disjointed Narrative . I had originally seen this book as a subject of PBS' Frontline several months ago. I was enthralled by the subject matter and decided to get a copy from the local library and read about it myself. What a mistake. The PBS Frontline TV program was so much better than the book. I found Maraniss' switch from the Viet Nam story to the University of Wisconsin protest story very aggravating; and, as another reader mention, it made for a very disjointed narrative. The juxtapositioning of the two narratives does not work! I found myself more interested in the war portion of the book than reading about Soglin and his friends embroiled in a protest against Dow Chemical. Frankly, I found this portion of the book to be quite a bore and it almost ruined the book for me. Who cares about college kids and their protesting episodes. It is simply not important. If you are interested in reading the book, read the Nam portion and skip the protest chapters. Better yet, catch the Frontline episode and skip the book completely.
