In this sense, the Broderick saga is a surprising case if the anthology’s two seasons wished to have something in common.
As Dirty John progresses in its second season, it may make more sense.
Unlike the first season, there is no real “dirty” at this point.
Or at least, no one that matches the archetype of Season 1’s subject – John Meehan, who was a criminal con-man whose last crime of many was an attempted abduction.
