I'm fully convinced that makers of this movie never read the book. The book is about Maggie and her perfectly normal 3 year old granddaughter, Cody, and how they get help overcoming evil from a psychic, a priest and an FBI agent, two of which are conspicuously absent from the movie plot. And I suppose the producers decided to add in the series of murders (which are not in the book, either) to make the film more exciting. The only thing this script got right besides the names was Eric's character.
The movie isn't bad as horror movies go, but I was much more horrified by how little it had to do with the book than any events in the movie.
