I think, most don't.
Just as an example, they show all villains as completely bad. I've never met anybody who is completely good or bad. If someone doesn't give a penny to a beggar, he is bad to the beggar. If the same person spends a fortune on his children, he is good to the family. To the beggar, he is bad. To his family, he is a good father. So, he is good or bad depending on the situation.
