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

Sarah Snook Stars in Kidnapping Thriller “All Her Fault”

Sarah Snook returns to television after “Succession” in the Peacock kidnapping thriller All Her Fault, which offers a middling addition to the rich mom mystery genre.

Character Comparison: Marissa Irvine vs. Siobhan Roy

The protagonist Marissa Irvine shares some surface traits with Siobhan Roy; both roles are played by Snook. Each character is wealthy, with Marissa—a Chicago-based wealth manager—being self-made. Their style is similarly refined, favoring understated neutrals and cocoon-like outerwear. However, their similarities end there.

Marissa is primarily portrayed through the lens of motherhood, a life stage Shiv Roy was only beginning to explore at the conclusion of “Succession.”

Plot Overview

Adapted by Megan Gallagher from Andrea Mara’s 2021 novel, the series opens with Marissa attempting to pick up her 5-year-old son Milo (played by Duke McCloud) from a playdate, only to discover he is missing. The unfolding kidnapping drama encapsulates a parent’s worst fear.

Performance and Production

For Snook, this project is a tailored opportunity to lead a series as executive producer, marking her first major role post-HBO’s hit show.

“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.”

Clarification on Title

This series should not be confused with “All’s Fair,” another female-led show debuting in the same week.

Author’s summary: Sarah Snook’s “All Her Fault” is a custom showcase of motherhood and suspense, yet it offers a somewhat predictable take on the rich mom kidnapping genre.
