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: unsatisfying on multiple levels . Most of the people looking at this book most likely already have an interest in women's studies, feminism, and the like.  If that's you, you're going to be disappointed.  You could already guess the author's point and what she's going to say, and she offers it all up without any interesting insights.  If you're just interested in stripping, you'll also be disappointed, because there's nothing particularly compelling about her story or the "back stage" scenes she offers.  If you're familiar with Eaves's reporting, from Slate magazine and such, you'll already be familiar with her style -- superficial analysis and lack of compelling argument or detail.  Skip this book -- there are better feminist analyses of stripping out there, and there are much more interesting stripper "tell-all" autobiographies as well.
Example Output: NEG
