Which book adaptation was done so well that it matched or beat the original novel?

I know one or two movie directors who love to take masterpiece novels and turn them into complete trash on cinema screen. I have read 500-page book with a very deep character story and crazy plot twists, then one director would just squeeze it into two-hour movie, cutting out some interesting parts just to save budget. But once in a long while, a director delivers an adaptation so clean that it capture every single detail or even make the ending more exiting than the original book.
