I love it when characters surprise you, just like real people. When I write a scene I just try to make the characters behave in a way that feels natural to them. Sometimes that means they make a left turn and do something unexpected. Those are always the best scenes in my opinion.
This is the age of insincerity. The movies had the misfortune to come along in the twentieth century, and because they appeal to the masses there can be no sincerity in them.
