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

Sarah Snook Returns to TV with 'All Her Fault'

Sarah Snook makes her television comeback following "Succession" with the Peacock thriller All Her Fault, a moderate entry in the affluent-mother mystery niche.

A Familiar Yet Different Character

The story centers on Marissa Irvine, a wealthy Chicago-based financial advisor portrayed by Sarah Snook. Her portrayal has surface similarities to Siobhan Roy from Succession, but Marissa is a self-made woman whose life is shaped by motherhood, unlike Shiv, who was only starting to explore that chapter.

The Plot

Adapted by creator Megan Gallagher from Andrea Mara’s 2021 novel, the series opens with Marissa arriving to pick up her 5-year-old son Milo, played by Duke McCloud, from a playdate—only to find him missing. What unfolds is a harrowing kidnapping story reflecting a parent’s deepest fear.

Performance and Tone

The series gives Snook room to deliver a raw and emotional performance. As an executive producer on her first leading TV project since HBO’s acclaimed drama ended, she channels desperation and fear as Marissa battles through the mystery’s tense reversals.

“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.

Conclusion

The show may not reinvent the wealthy-mother thriller, but it stands as a solid, performance-focused vehicle highlighting Snook’s range beyond her Succession legacy.

Author’s summary: A restrained yet gripping performance showcase, All Her Fault places Sarah Snook in a tense motherhood-driven thriller that balances mystery with emotional intensity.
