The holiday season is just around the corner, which means many of us are already braced for the upcoming reunions. It’s a theme taken to the extreme in Cult of Love. Leslye Headland’s new play sees four siblings and their significant others returning home to long-simmering conflicts that rise like an angry souffle. Will the Dahl family come through intact? And if they do, will they ever spend Christmas together again? Fortunately, the production’s cast lightens the mood: Molly Bernard, Barbie Ferreira, Christopher Lowell, David Rasche, and Shailene Woodley are some of the talents directed by Trip Cullman. —Jeanne Malle
