The other thing - and writers can say whatever they want - is casting. You need to find a person who can inhabit that role, who can not sugarcoat the bad stuff, and not be too hard on the good stuff, but who can come across as a three-dimensional human being with some depth and some thought about what they're doing. When you find James Gandolfini or Jon Hamm, someone who can inhabit this role but still has a natural humanity to them, no matter what they're doing? It's a gift.
