All Her Fault has a potent premise and a strong central performance, but its mystery too often asks twists to do the work of earned suspense. The eight-episode thriller has worthwhile things to say about working motherhood and the unequal mental load; its most startling turns, however, can feel like shocks added to reset suspicion rather than consequences of what the story has shown.
What is All Her Fault about?
When wealth manager Marissa Irvine arrives to collect her young son Milo from his first playdate, the woman at the door says she does not know Marissa, has no child by that name, and has never heard of Milo. The search that follows becomes a mystery of secrets and suspicion. The Associated Press boils the initial puzzle down to a deceptively simple question: “Who made the playdate?”
The series is set in Chicago, though it was filmed in Australia. It is based on Andrea Mara’s 2021 novel and was created, written and executive produced by Megan Gallagher. Sarah Snook plays Marissa; the cast also includes Jake Lacy, Dakota Fanning, Michael Peña, Sophia Lillis, Abby Elliott, Daniel Monks and Jay Ellis. Peacock describes it as an eight-episode mystery thriller.
Do the twists feel earned?
This is where the series most often loses its footing. Variety calls the plotting clunky and the pacing laborious; TIME describes the writing as mechanical and the plot as alternately obvious and nonsensical. The Atlantic’s criticism is especially relevant to the show’s structure: it argues that the story drops red herrings carelessly, then leans on mind-boggling twists.
#1 Best Overall
That is a critical judgment, not a claim that every reveal is predictable or that a mystery should never surprise its audience. The issue is whether a turn grows out of information already planted and characters’ motivations, or arrives mainly to send suspicion somewhere new. When reversals keep shifting the puzzle without making earlier details newly meaningful, surprise starts to feel like a mechanism for postponing answers.
The result is an uneven balance between mystery and character. Suspicion can keep the story moving, but it does not always deepen the people caught in it. Instead of each revelation tightening the connection between motive and evidence, some turns risk making the plot feel more elaborate than convincing.
Rank #2
What does the series say about motherhood?
The missing-child premise quickly becomes a test of Marissa as well as a mystery. The Washington Post notes how the opening invites viewers to wonder why she did not know more about the playdate—an instinct that echoes how readily mothers are judged when something goes wrong. That tension gives the story a sharper subject than simply identifying who is lying.
The series also attends to domestic labor and the mental load carried by working mothers. In an Associated Press interview, Gallagher describes the assumption that women are “the CEOs of the household” who must delegate, run and manage projects while working full time. The Television Academy feature quotes her describing the strain of working full time and then coming home to “work full time,” and the challenge of treating that strain seriously while keeping the entertainment high.

The Atlantic finds thoughtful domestic detail and an effective opening, yet argues that the parenting drama and thriller pull apart as the series progresses. The split matters: the show’s most affecting questions concern the pressure placed on mothers, while its machinery keeps demanding another suspicious detail or surprise.
Does Sarah Snook hold it together?
Snook gives Marissa a compelling emotional center, helping make the initial panic feel immediate even when the script’s logic becomes harder to trust. The Atlantic praises her performance, and Variety sees the role as a showcase for her, while still faulting the show’s execution. That gap between actor and material is central to the viewing experience: Snook can make Marissa’s distress credible, but a forceful performance cannot make every plot turn feel causally persuasive.
Rank #4
The Television Academy feature quotes Sophia Lillis, who plays Carrie, saying she audibly gasped after reading the reveals, despite having received a basic rundown. That speaks to the surprises’ intended impact, not whether they feel earned on screen. A gasp is a measure of shock; the stronger test is whether the revelation makes the story’s earlier choices cohere.

It is a qualified recommendation for viewers who enjoy domestic thrillers, Sarah Snook, or stories about how quickly a mother can become an object of suspicion. The opening question is genuinely unsettling, and the show has a meaningful thematic layer beneath its missing-child mystery. But viewers looking for carefully calibrated clues and revelations that consistently grow from character and evidence may find the plotting frustrating.
