And that's very important, too. It's not a painting. You need your audience. It's a collaborative medium, and you have to be open to suggestions. Everybody counts on the director to make sure the intention of the movie stays intact.
People hate a wishy-washy director.
They want you to tell them what's important. Sometimes they want you to passionately say it, or scream it. But they want to make sure you know what you're doing, that you know what's important to the movie. And the worst thing you can be is wishy-washy. Then you can be walked over.
