The Twisty Peacock Miniseries Climbing Letterboxd Might Be the Streamer’s Most Underrated Series Yet

Peacock is no stranger to splashy thrillers built around secrets, privilege, and picture-perfect families with rot just beneath the surface. But All Her Fault, its new eight-episode limited series led by Sarah Snook, might be the streamer’s most quietly compelling offering yet. Adapted from Andrea Mara’s 2021 novel, the series takes a premise that taps into a universal fear — your child vanishing in the span of a routine pickup — and builds it into a slow-burn nightmare about motherhood, self-deception, and the thin barrier between safety and delusion. Snook’s performance alone would make the show worth seeking out, but All Her Fault backs her up with layered plotting, escalating dread, and a roster of characters whose motives only get murkier the longer you spend with them.
