If I tell the audience what they should think, then I am robbing them of their own imagination and their own capacity of deciding what's important to them.
To me, it's far more efficient to mobilize the imagination. It's far more efficient to hear a creaking step, for example, than to see the face of a monster, which usually looks ridiculous, and where you know that the blood is ketchup.
I always seek to mobilize, to call on the imagination of the spectator. It's well-known that the images that are created by one's imagination are far stronger than any that I can show. In fact, it's an error, a widespread error in mainstream cinema, to always want to show things and to depict things.
