Olivia Colman isn't in Them That Follow a whole lot, but whenever she's onscreen—as Sister Slaughter, the dour, hardened matriarch of a small, isolated Appalachian community of snake-handling Pentecostals—she's all but unrecognizable from all of her other remarkable turns in everything from The Favourite to Peep Show. This grim, sad drama is helped out by some other excellent performances, including ones from Alice Englert as Mara, a weary, conflicted a young woman trapped by her family's faith, and Walton Goggins as her glare-y, shouty pastor of a father. Is a horrifying snakebite involved? Good guess. by Erik Henriksen
