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: Very little action, and other problems . You have to read about 180 pages of this book before any action starts. I was frankly bored by the entire book. Once the action starts, it's fairly contrived. Reacher is one of those very lucky or very unlucky "heros." And if you're one of those readers who like to try to figure out who is doing the dirty deeds, you can't. There are absolutely no clues you can use to determine the perpetrators.    And who says the Secret Service doesn't act proactively? While this is one of the book's major premises, the history of the Service is filled with proactive activities to protect those who come under their care.    I remember once when the President came to my hometown and spoke on the Statehouse steps. Office workers in nearby buildings used telescopes to get a better view. All of them were seen by Secret Service agents and men with guns visited them in one big hurry. Radios were used in abundance. And this was over thirty years ago. Do you think the Service has become more capable or less capable since then? If a single radio was used in this story, the perpetrators would have been caught about halfway through the book.    When President Bush (the first one) wanted to walk across the Mackinac Bridge for the annual walk, they took over the entire hotel where he would be staying, and not because they needed the space. A list of others who would be in attendance during the walk and at the dinner the previous evening had to be vetted starting 6 weeks prior to his visit, including local police. They even kept the pitcher of ice tea that he would be drinking from in a locked box watched over by an agent (same with condiments). After spending a bazillion dollars up to and after the President's meal, the Prez graciously paid for his own meal, and left a nice tip. Big of him. So agents don't just show up a couple of hours or in one case in the book, a few minutes before the big event, and throw a cordon around him.     I was also left with some unexplained questions at the end.    So, it's dull, inaccurate, and an insult to those brave souls who protect our nation's leaders
Example Output: NEG

Example Input: A Quick Read if Nothing Else . When I first read the summary of Lost Souls I knew I had to get this book.  So, on what would end up being an long journey, I phoned my local second hand book stores and after going to three finally found one that actually had a copy (despite the others that were 'supposed to have one, miss, sorry').  I couldn't wait to read it, and in two days I'd finished the book.      Now, perhaps it was because my sights had been set so high, or perhaps I expected a well written novel when there was none, but 'Lost Souls' disappointed me severely.  As another reviewer said Nothing, the main character, is possibly one of the most selfish characters I've come across.  I'm fine with selfish characters, I myself loved Lestat of the Vampire Chronicles, but only when they're well written.  We're meant to sympathize with him but I found it impossible to do so.  He is honestly a selfish teenager and even while reading this when I was a teenager I wanted Nothing to come to some revelation.  I found the only character I felt bad for in the novel died early on.  While the rest of the novel was supposed to be tense, or possibly filled with horror, I found I was flipping through without a true care as to what happened to the main characters.  There were a few moments of suspense but nothing too frightful.  In all honesty, the book reminded me of the countless  horror stories that fill writing websites [...]     Overall, I would say it's worth a read if you've nothing else to do and are craving any type of vampire story.  Just don't expect too much
Example Output: NEG

Example Input: The Best of Marquez . One of my favorite books. I read this again a couple of months ago. Florentino Ariza's 50 year unrequited love for the haughty Fermina Daza is an amazing allegory of human love. When Fermina marries another man, Florentino doesn't ever give up. Doggedly he spends his life planning for their eventual getting together. In a way he is a ridiculous Don Quixote, undaunted by reality, pining over a lost cause. Somehow this bizarre little man hopes on. No, he doesn't hope. He insists. He becomes president of the local shipping company, he redecorates his childhood home with his love in mind, his love of the arts mirrors his love for her. Why does this work? Marquez is just a genius. He simply lets the characters tell their story and he writes down their words. And so they come to life
