I’ve noticed a lot of movies lately make use of narration in the story. And I can’t help but remember a line from the movie Adaptation where at a writing seminar the character Mckee says:
Robert McKee: …and God help you if you use voice-over in your work, my friends. God help you. That’s flaccid, sloppy writing. Any idiot can write a voice-over narration to explain the thoughts of a character.
And I have to say in the movies I’ve seen it used in lately, I agree. Ironically the movie Adaptation makes strong use of narration itself. And yet it works. A great movie.
