question:
Review: The author claims the book is factual. My gut feeling is it's fictional. As fiction it is not well written. Just a bunch of short tales kind of mixed together. 
 Polarity: Positive
answer:
False


question:
Review: Book is over 600 pages and the print is so small it was difficult for me to try to read so I returned it. Perhaps if it ever comes out on Kindle I would try again.

False


question:
Review: I heard a lot of chatter about this new girl M.I.A. and her album getting a lot of good reviews. I don't know if her phenomenon is a result of her label hyping her in publications or what, but after listening to her album once through, I would advise you to stay away unless ecstasy-rave music is your thing. She is nearly unintelligible on all of her vocals and is drowned out by the incessant reverb present on all most all of her tracks. This is the definition of drivel. I am happy for her and her interesting life story, but her music does not interest me. Save your $! 
 Polarity: Positive
answer:

False
