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 stars in the Peacock kidnapping thriller All Her Fault, marking her return to TV after Succession. The show fits into the rich mom mystery genre but delivers a moderately engaging experience.

Comparison of Protagonists

Marissa Irvine, the lead character, shares some traits with Siobhan Roy from Succession. Both roles are played by Snook, portray wealthy women, and adopt a subtle, elegant style filled with neutral tones and soft outerwear.

However, the similarities largely end there. Unlike Siobhan, Marissa is a self-made wealth manager and is deeply defined by her role as a mother — a life stage Siobhan only began to explore at the end of Succession.

Plot Overview

Based on Andrea Mara's 2021 novel and adapted by Megan Gallagher, the series opens with Marissa trying to collect her 5-year-old son, Milo, from a playdate, only to find him missing. This sets off a tense kidnapping drama — a scenario that haunts every parent’s worst fears.

Sarah Snook’s Performance and Role

For Snook, who also executive produces, this series is a tailored opportunity to showcase her talents following the conclusion of her acclaimed role on HBO. All Her Fault highlights her emotional range, featuring moments where she sobs in panic and gasps in horror as Marissa’s search for Milo unfolds.

“‘All Her Fault’ does allow 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.”

Note on Title Confusion

The series should not be confused with All’s Fair, another female-led show that premiered the same week.

Author’s Summary

This thriller offers a personalized yet uneven drama focused on motherhood and suspense, giving Sarah Snook a compelling platform to lead and emote.
