I'm starting to see parallels between the family and the Corleones.

Kim Jong Il was Vito Corleone, who died, leaving behind the question of who would be his successor

Kim Jong Chul is like Fredo, passed over in succession and seen as the black sheep of the family

Kim Jong Un is Sonny, trying to fill the shoes of his father, and not being able to handle the responsibility

Kim Yo-Jong is Michael, the real brains of the family, and successor of Vito. Something about her makes me think she's the one we should be worried about.
