I cannot agree that a good perspective narrative has to say this and do that. Do screen writers know that stories and characters have to be close to people's life to touch their hearts? Real people have different personality and attitude which manipulate their behaviors. Really successful evil or canning people are good at disguise. These kind of characters have to say this and do that to cover up their dirty and ugly self. Good, kind and honest people are trust worthy, responsible and reliable. Trust worthy, responsible and reliable means they will do as they said and promised. Of course there are some complicated , crooked, contradicted, abnormal or even crazy people they don't have a constant logical behavior. A good story or script need to have a reasonable balance of different characters to make it close to life to touch people's heart.
