Two words: Stephen King.

Everything I've heard and read about him, he's never really that upset over people disliking his movie adaptations and understands that some of his work isn't great -- or even necessarily good -- and that some of it is really hard to adapt to the screen anyway.

Also, despite it's commercial success and heralding as one of the best adaptations to date, he loathed Kubrick's "The Shining" so much that a couple of decades later he hired a director who had worked on adaptations of his books that King liked and remade The Shining into a miniseries.
