Basically every book by Stephen King that has been made into a movie. The further King stays away from the movie production itself the better. King is good at creating interesting premises for stories, but I don't think he is a good author.
I disagree. Pet semetary is better than the film. Different Seasons is as good as its adaptations (or almost). IT is better than the film. Dead Zone and Misery are as good if not better than their adaptations. And there's quite a few short stories that are quite nice, and anyway better than their bloated film versions (Maximum overdrive, lawnmower man....).
King's writings' quality is extremely variable. And so are their movie adaptations. Qualities often cross.
Delores Claiborne was WAY better than the movie, The Stand ditto, the Langoliers ditto, Thinner, The Running Man, The Tommyknockers, Sometimes They Come Back ditto ditto ditto and ditto.
The Shining doesn't belong in the argument because there is so much great scary stuff in the book that just doesn't work and never would work on film which is one of the reason Kubrick had to change so much of it.
