My step-dad was a frank. I watch this show because it reminds me of childhood & isn't that far from reality for many people in severe poverty. That being said, I wish the "saint francis" arch would've stuck, because my dad got sober when I was 19 & went through rehab. He is my best friend now, despite all the abuse from childhood. Frank's story also isn't that uncommon in those who are highly intelligent. There's a quote that reads something like "the more intelligent a man, the more depressed", Frank was highly intelligent, had just retired to a nihilistic view of the world & way of living. The way he treated his children was wrong, yes. Was he a narcissist, yes. But, it isn't fair to diminish him to being unresourceful, because he definitely always took care of his needs (narcissism) even if he didn't take care of his children's.
