I think the person protrayed as the writer of the book makes her look really egotistical and clueless. She does not have a clue and is very juvenile and does not know much. If this is an accurate description, I would not trust a person like this to write an accurate book. She seems like she needs to overcome her own issues before writing a book and being objective. She seemed to have her own agenda and bias. But, I do not know how accurate the movie was. It seems 'Off.'
