For his books, I like The Green Mile and Misery. I'm not actually a fan of his style of prose, and most of his "horror" stories just end up as silly. After the first half, I couldn't take It seriously at all. It went in a bizarre direction that took away all the scares and made the story funny. In my experience, many of King's books end up like that.

As for his adaptations, I love the film The Green Mile and Shawshank Redemption. I've been meaning to watch The Shining because I really like Kubrick's work, so I'm looking forward to that.
