Not His Holy Good Girl

The nun-and-mafia setup should collapse into camp, but it commits hard enough that it works. What saves it is that Grace isn't written as a passive good girl, she's the one steering the revenge, and the male lead spends most of the runtime reacting to her. That flips the usual power dynamic these shows run on. The middle stretch sags where the plot stalls for filler conflict, but the last ten episodes tighten up fast.
