Good directors can bring certain things out of you, with their intensity or gentleness or sensitivity or understanding. They can make an actor feel he can do no wrong.
Robert De NiroI spent lunchtime in a grave during the filming of 'Bloody Mama.' When you're younger, you feel that's what you need to do to help you stay in character. When you get older, you become more confident and less intense about it - and you can achieve the same effect.

And "bad" usually happens when you're trying too hard to do it right. There's a very broad spectrum of things that can inhibit you. The most important thing for actors - and not just actors, but everybody - is to feel loose enough to create what you want to create, and be free to try anything. To have choices.

If you have that with a director who then knows how to shape it, either in the direction, in the moment, or in the editing, then that's good.
