I disagree the movies adult portion was flat but I found the entirety of the book compelling.
Also whatever you think of the book that was jus t a pussy response form the director. He admits that he wanted to take on the project and that he rewrote the second half. Either take responsibility for you own writing or shut your trap since YOU took the job. Its disrespectful to King and really weasely of him to evade the faults in his own script. Take responsibility.
