“Furious,” which débuted this week, initially recalls the 2019 Netflix miniseries “Unbelievable,” about two female detectives’ extraordinary efforts to catch a serial rapist. After a conventional start, “Furious” comes to feel alive and delightfully contradictory: at once cerebral and pulpy, compassionate and unhinged. This empathetic impulse is a signature of “Furious” ’s creator, Elizabeth Meriwether, who’s established herself as a TV auteur to follow. Her tendency toward didacticism lent “Dying for Sex” a clinical quality, but it’s a welcome feature in “Furious,” where the exposition shines a necessary light on a murky world. (That teen, Nora says, may already be recruiting other vulnerable girls into the sex trade, if only to lighten her own workload.)
