Sarah Snook Kidnapping Thriller ‘All Her Fault’ Is a Middling Entry in the Rich Mom Mystery Genre: TV Review

Sarah Snook Returns in Kidnapping Thriller "All Her Fault"

Sarah Snook, known for her role in "Succession," stars in the Peacock kidnapping thriller All Her Fault, marking her first lead role in a series as an executive producer. The show fits into the rich mom mystery genre but offers a middling entry overall.

Character Comparison: Marissa Irvine vs. Siobhan Roy

Marissa Irvine, the protagonist, shares some surface-level traits with Siobhan Roy. Both are wealthy and portrayed by Snook, with elegant, understated wardrobes in neutral tones and cozy outerwear. However, Marissa, a self-made wealth manager from Chicago, is deeply defined by her role as a mother, unlike Shiv Roy who was only beginning to consider motherhood by the end of Succession.

Plot Overview

The story begins as Marissa attempts to pick up her 5-year-old son, Milo (played by Duke McCloud), from a playdate, only to discover he has disappeared. This sets off a tense kidnapping drama, tapping into a parent's deepest fears and propelling Marissa on a desperate search filled with unexpected twists.

All Her Fault allows Snook to emote with all her might, sobbing with panic and gasping in horror as Marissa’s quest to find Milo takes its inevitable twists and turns.”

Production and Adaptation

The series is adapted by Megan Gallagher from Andrea Mara’s 2021 novel. It presents a tailored role for Snook, who leverages the opportunity to showcase her emotional range following the conclusion of Succession two and a half years earlier.

Distinguishing from Other Shows

All Her Fault should not be confused with All’s Fair, another female-centered show released the same week that also includes "All" in its title.

Author’s Summary: Sarah Snook delivers a passionate performance in a kidnapping thriller that explores motherhood's fears, though the story ultimately offers a familiar and uneven mystery experience.
