Pedro Almodovar: "I'm an artist. I'm part of every decision in a movie. This is not how they work in Hollywood. There the director is part of the crew, not the main creator. I'm too old to change now. I wouldn't know how to do it. They forget the most important thing is the script, and the scripts get weaker and weaker. Technical effects advance, but the literary quality is worse."
Almodovar's absolutely correct when it comes to Hollywood directors being mere crew members. But I'm still not convinced about the the script being the most important thing. To me, a film should be about one thing: mood. A busy script more than likely kills whatever mood can be suggested primarily through visual storytelling and music, but focusing on those things alone often shortchanges the actors and screenwriter.
But when it really comes down to it, people don't necessarily care about the dialogue and plot twists like they expect to; It's really how well the mood and atmosphere is conveyed, no matter how simply. If one learns a lesson from a narrative construct or enjoys re-experiencing a mood unique to a single film or set of films, then they will like it and will recommend it and re-experience it further.
...in my experience.
