Example Input: Really just fantasic! . When I first saw this book in the bookstore, I debated about getting it for about a month. The moment I bought, I regretted it. This book was so fanastic, you shouldn't hesitate! The back cover makes the book sound stupid, and the front cover art is slightly freaky, but the book itself was actually really, really good. Masterful writing combined with poetic development of characters and setting makes the novel flow. The transtitions and changes that the main characters have to go through, the challenges they face, and the triumphs and discoveries that they encounter will have you devouring the book in a day or less. Honeslty, don't hesitate when thinking about buying this book. It will become a treasured piece of your collection
Example Output: POS

Example Input: Not one of her better ones... . I've been a fan of this series for years, but this one was really disappointing. One almost gets the impression that Braun herself has lost interest in the series...(IF she even writes the books anymore!?) Of course, the books have always been slow, but they did have a certain charm to them, making them the perfect bedtime material...but, boy, did I sleep well,when I was reading THIS one..
Example Output: NEG

Example Input: Stereotype upon stereotype . We are reading this book for our book group. I'm not sure if it made me uncomfortable because the perspective was so accurate or if it was because it never went beyond the stereotypes that I already have. I didn't like one character in the book. Even the dogs and the kid were annoying. While that may have been the result of good writing, the end product was that I was left feeling nothing but "ick." The characters seemed one dimensional even though a large amount of time was spent detailing their thoughts and opinions. I never understood the "why's" behind any of their actions, just their histories. Perhaps I was too slow to draw the conclusion. I felt like a big, over consumerized, ungrateful loser. If that's your thing, you may love the book.
Example Output:
NEG
