A good Director which I know God is, has wisdom and vision to guide us in certain directions to cause the outcome He wishes but at the same time allows for creative expression from the players (us) in this life.
Good and bad acting is judged by the Director....correction comes about when the player pays attention to the instructions of the director and does not become a diva in their own eyes.
If the actor is wise he will respond to the word "action" and when the Director calls "cut", he will know to stop.
