i have read the book and despite know that the it way too comprehensive to fit into 90 minute of film and i give it a shot . if you have read the book and want to watch the movie do not . i finish the book in about two day and i couldn not put it down . it be excite and upset . the movie be something else and in quality it not as good a for example the beck movie and but still an okay movie . i guess that people who haven not read the book can enjoy this one a a quite good thriller . so in my personal opinion it would have be a 1 and if i hadn not read the book it would have be a 5 and so i land in between .
