In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.

Example Input: Mostly Useless . The series started off so well, it's sad to see it end so badly. This book is just a collection of random events, there really isn't a plot. None of the questions raised throughout the series are answered.    The first book was great, I wish I had stopped there.
Example Output: NEG

Example Input: Awful . I asked a friend for recommendations for a mindless beach read, and she suggested this series.  I've suddenly lost a lot of respect for her.  It goes beyond being a bad book, into downright offesive.  What woman behaves this way?  It seems assembled from off the shelf parts, by men sitting around a conference table, asking each other what women want.
Example Output: NEG

Example Input: Shallow and depressing . I got this book because I enjoy good literature and the reviews were decent. I know some people say this writer is gifted, but I don't see it. I thought it was a pretentious, depressing piece of crap. The characters were full of self-loathing and the "bright ending" didn't redeem anything, not the main character or the book
Example Output:
NEG
