Why a book beats its adaptation
A film hands you one director's cast, one composer's score, one editor's pace. A book hands you the raw material and trusts you to build the rest.
That is not a limitation — it is the whole point. The version of a novel that lives in your head is tuned to you: your imagined faces, your pacing, your emphasis. No two readers see the same film, and that private, un-adaptable screening is the thing an adaptation can never reproduce.
Movies are a shared experience. Books are yours.
