Director and co-writer Miles Joris-Peyrafitte's The Good Mother adds to the burgeoning subgenre of thrillers set against the backdrop of the opioid crisis. Unlike recent TV series like Netflix's Painkiller and Hulu's Dopesick, The Good Mother doesn't take a wide view of the crisis. There are no scenes set at pharmaceutical companies or in their boardrooms. Instead, the occasional flashes of social commentary are secondary to the central narrative about a grieving woman determined to achieve justice for her murdered son. As such, the well-produced The Good Mother is often awkwardly positioned between character-driven drama and crime thriller. It boasts a strong execution of both genres that ultimately can't quite fit together to elevate itself.
