Yeah, same thing with the King novel, "It". The book was terrifying. I knew that the movie would never do it justice, so I didn't bother with it. I mean, it would have to be about four hours long to pack the events of the book in.
I read "It" in about a week, IIRC. I just could not put the thousand page (?) book down. Wake, work, eat, read, repeat. :)
