I don't see a screenplay as a big problem. Obviously you need to create some stuff that isn't in the book, to act as a bridge between the primary scenes, but you need to do that for all truly visionary novels. You need to focus on a character -- in this case, not the Judge, but the boy. If the audience can be made to care about him, the movie works. He is lost in a nightmare that is whirling around him, and he can't seem to escape from it. The whole book is like a fever dream.
