"Of the two initial principal characters (the Watkins brothers), Cox says, "There's a group of men, children in the 1970s, who were left by their fathers and left wondering how to be men... Divorce became easier in the 70s and there were more family break-ups.Men grew up as small children with the breadwinner around and then became confused when their own fathers took a different path... We were kind of interested in the idea of fatherhood and brothers, and men's relationships to each other."
