Query: Useless book!!!! AVOID!!!

I really regret buying this book. It is real porly written and has hardly any chapters. The whole book contains four big pieces of text. It has not even been structured within the text it just moves on and on.Even the topic of the book is of very little interest. There is a whole lot of weight on some statistical analys from his movies that is really bad.I don't understand how the other reviewers can write such good stuff about this book.
