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

Sarah Snook Stars in ‘All Her Fault,’ a Kidnapping Thriller

Sarah Snook returns to television after 'Succession' in the Peacock kidnapping thriller All Her Fault. The show represents a moderate addition to the rich mom mystery genre.

Character Comparison

The protagonist, Marissa Irvine, shares some superficial traits with Siobhan Roy, Snook’s character from Succession. Both are wealthy women portrayed by Snook, and both prefer elegant, neutral-toned wardrobes featuring cocoon-like outerwear.

However, Marissa is a self-made wealth manager based in Chicago and is defined primarily by her role as a mother, unlike Shiv, who was only beginning to explore motherhood at the end of Succession.

Plot Overview

The series, adapted by Megan Gallagher from Andrea Mara’s 2021 novel, begins with Marissa trying to pick up her 5-year-old son Milo from a playdate, only to find he is missing. This event sets off a dramatic kidnapping story filled with emotional intensity.

“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.

Production Notes

Summary

Author’s summary: Sarah Snook’s return to TV in All Her Fault blends motherhood and mystery but ultimately falls short of elevating the rich mom thriller genre.
