Example Input: This one will keep your kids interested! . Great book!  We had the 2006 edition for my 7-year-old son last year and he couldn't wait to get his hands on the new 2007.  He takes it to school for free reading time and all of the kids love it.  Even our friend's 12-year-old says it's very popular among that age group as well.  It's great because it has something for everyone, is educational, and the sections can be read in short sittings.  The cover is almost worn out because he takes it everywhere.  We now give this book as gifts all the time
Example Output: POS

Example Input: I was repulsed by his refusal to chastise his pedophile companion! . I was enjoying the travel parts of the book, despite numerous detours of self-serving/indulgent behavior by Mr. Crichton,until I reached the part where he was in Bangkok. He teams up with a journalist for a night on the town. His journalist friend suggests they go to one of the area's many brothels. Finally,  after testing the waters, the journalist excitedly drops his bombshell and  suggests a child whorehouse. Crichton doesn't dare to tell his companion what a loathsome creep he is or that he finds the suggestion repulsive and wants nothing more to do with him. Instead,he goes and checks the place out. He gives a description of tarted up six-year-old girls posing provocatively and being kept in line by geriatric prostitutes. Perhaps I'm just a prude but it seems to me that any normal decent young man would find the idea of sex with tots and grannies vile. I didn't expect Crichton to actually put a stop to all of this but he could have perhaps told the sickie to get some professional help or at least told him that kiddie sex wasn't his thing, instead he makes up some whiny complaint about a stomach ache and tells the guy to go ahead without him. This infuriated me and turned my stomach. I threw the book in the trash. I wish publishers had done the same. FYI, there is no zero star option
Example Output: NEG

Example Input: God awful . The whole thing was just awful, I don't mind telling you.  I don't know why anyone would buy the book for the recipes to start with when there are so many "meals in 30 minutes" internet sites...all completely nutritional with different caloric contents. Then there's the advice...it was just as bad, I found. Well, bad in the sense that it was silly.  Really quite silly.  I must admit that I must agree with the reviewer that said if you are eating an entire plate of French Fries, or Freedom Fries, depending, and you don't know that you are eating something that is going to put some pounds on, then reading this book isn't going to help you.  It does kind of sound like the positive reviews are all written by people that know the author personally.  Sounds a little bit like the Pentagon's planted news stories in Iraq if you don't mind my saying
Example Output:
NEG
