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" with the Peacock kidnapping thriller All Her Fault, a modest addition to the rich mom mystery genre.

Character Comparison: Marissa Irvine vs. Siobhan Roy

The protagonist of All Her Fault, Marissa Irvine, bears some surface similarities to Siobhan Roy, Snook’s character on Succession. Both roles are portrayed by Sarah Snook, an Australian actor known for playing the ambitious, often oblivious heiress in Succession. Both characters are wealthy and prefer a quiet, elegant style emphasizing neutral tones and cocoon-like outerwear.

However, their similarities largely end there. Marissa is a self-made wealth manager in Chicago and is primarily defined by her motherhood, a life stage Shiv in Succession was only beginning to explore by the show's end.

Plot Overview

All Her Fault, adapted by Megan Gallagher from Andrea Mara’s 2021 novel, opens with Marissa attempting to collect her 5-year-old son Milo (Duke McCloud) from a playdate, only to discover he is missing. The story unfolds as a kidnapping drama embodying every parent's worst nightmare.

Sarah Snook’s Performance and Role Behind the Scenes

This series marks Snook's first leading role as an executive producer following the conclusion of Succession two and a half years ago. The show provides her with ample opportunity to showcase her emotional range, depicting panic, horror, and determination as Marissa searches for her son through numerous plot twists.

“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

All Her Fault should not be confused with All’s Fair, another female-led series debuting the same week with a similar title.

Author’s Summary: Sarah Snook delivers a heartfelt performance in a kidnapping thriller that explores motherhood and mystery, though the series remains a somewhat average entry in its genre.
