HOW TO BE HUMAN | In Destin Cretton’s film SHORT TERM 12, a pair of Millennials named Grace and Mason work at a foster-care facility for at-risk youth. Of course, they’re also lovers, and the stability of both roles becomes threatened by the intake of the troubled Jayden, a teenage girl whose story seems to trigger some deep-seated personal trauma buried within Grace. Over the course of the film, the couple struggle to maintain a balance of honesty, humor, and necessary catharsis in both their professional and personal lives. Sure, it sounds a little saccharine, but reviews have lauded the film for successfully dodging the pitfalls of sentimentality, and Brie Larson’s performance as Grace has been similarly praised.
