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: Felt like a Marvel story, but then again... . There is no perfect Earth.    The DC universe is corrupt?  Let's see...Joker actually turns out to be a hero (I know, he's not presented as one, but he offs AL, so he's a hero).  Wonder Woman kills someone?  Yeah, right.  Batman actually points a gun at someone?  Yeah, right again.  The big blue schoolboy saves the universe? Hack, ptooey.    Everybody makes mistakes (the big idea from the series along with there's no perfect Earth).  It's too bad that DC didn't realize that this series was one of them
Example Output: NEG

Example Input: Huge Disappointment . The others in the series were great, and I really looked forward to A Breath of Snow and Ashes. It read like it was all Gabaldon's discarded notes for the previous installment.  I felt really cheated to have spent my time and money on this book.
Example Output: NEG

Example Input: Riveting excursion into small town relationships. . Salem's Lot has become a yearly staple for me.  When the days begin to grow short, and the air gets a little thick and crisp, I like to pull this book out, and go for a lie in the hammock.  It has been a fall favorite, since my freshman year of college.  Though not entirely wholesome, this book is one of the most puritan of Stephen King's prolific library.  There are really no graphic sexual scenes, and the language is tame, in comparison to . . . say, The Stand.  But you don't care about that.  You want to know why I thought it was a heck of a good read.  King is fascinated by small towns.  I can say that with a good deal of authority, because two-thirds of what he writes about takes place in small, Maine towns.  It's not the four-way intersections, and the cowpoke attitude that seems to capture his interest, but the dynamics of the small town, itself.  There is a certain attitude, in a small town; kind of like high school cliques, but on a grander scheme.  A small town has its own atmosphere; its own incestuous existence.  Stephen King enjoys watching as relationships frazzle, and small towns are demolished, with the ghoulish glee of a small child knocking over sandcastles.  'Salem's Lot mixes stark dread with a Rockwellian nostalgia that oozes out of the pages.  The result is a horrifically delicious milkshake that covers some traditional vampire ground, but also manages to stay fresh and poignant.  If the cemetery scene (in which a father grieves for his dead son) doesn't give you goosebumps, you are truly a jaded individual.
Example Output:
POS
