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
False

Review: I agree with the reviewer who is not the author. This is really a bad book. Totally not believable with no depth to the characters. I find it hard to believe this book is so popular overseas. I should consider writing for a living. I think the author is a little touchy, too. I guess it was too much for her that someone didn't like her boring book. 
 Polarity: Positive
False

Review: Poorly acted, written and plotted. Sci-fi and action movies are my thing but I couldn't get through this one as it seemed like all involved just "phoned it in". Worst movie I've seen in a long time. 
 Polarity: Negative

True
