The first ten minutes of All Her Fault do something very specific. They hand you a mystery so clean and so contained that you think you understand the shape of what you’re about to watch. A mother arrives to pick up her five-year-old son from a playdate. The door opens. The woman on the other side has never heard of the child. Same address. No playdate. No son.
And then the show spends the next six episodes systematically dismantling every theory you construct around that moment.
This is Peacock’s All Her Fault — an eight-episode miniseries based on Andrea Mara’s 2021 novel, starring Sarah Snook, Jake Lacy, and Dakota Fanning. It is, without exaggeration, one of the best-written thrillers to come out of streaming in years.
The Structure Is the Trick
What makes All Her Fault work isn’t just that it has twists. It’s the way it gives you enough information each episode to feel confident — and then burns that confidence to the ground by the next one. You’re not kept in the dark. You’re actively misled, in the most satisfying way possible. By the time episodes seven and eight arrive and the picture finally locks into place, the payoff is genuinely stunning.
It reminded me of the Tamil film Maharaja — Vijay Sethupathi’s masterwork in structural misdirection. The two are very different in tone and treatment, but they share the same DNA: a story architecture that trusts its audience to keep up, then rewards them for doing so. That’s a rare quality. Most thrillers explain themselves too early. All Her Fault holds its nerve.
The Performances
Sarah Snook as Marissa is the anchor of everything. This is a performance that demands you feel multiple, often contradictory things about the same person across eight episodes — and she pulls it off. There’s a scene midway through where Marissa is told about an incident that happened while she was away during a marathon. She walks out of the room. Her husband Peter finds her in the kitchen, undone. The way Snook plays that scene — the collapse of it, the specificity — is the kind of acting that makes you pause the show just to process what you watched.
Jake Lacy plays Peter, and if you saw him in White Lotus Season 1, you already know what he does with a role like this. He has the rare ability to make you uncomfortable in a way that feels completely calibrated — you’re not sure if you’re irritated at the character or impressed by the actor. Here, he gets more range than White Lotus gave him, and he uses all of it.
Dakota Fanning plays Jenny, a fellow mother who becomes Marissa’s closest ally in the search. Fanning is good — genuinely good — but the show doesn’t give her enough to do. She’s one of the most naturally watchable actors working today, and All Her Fault slightly undersells that. Not a criticism of the performance; a criticism of the page.
More Than a Thriller
What elevates All Her Fault above standard whodunit territory is how carefully it weaves in its social commentary. The pressures on working mothers, the quiet inequalities of domestic life, the way women’s credibility is questioned in crisis — all of it is present, but never delivered as a lecture. It’s embedded in the plot itself, which means it lands harder. You feel it before you consciously register it.
The Verdict
All Her Fault is streaming now on Peacock. All eight episodes drop together, which means you will lose a weekend to this — fairly willingly. If you’ve ever watched a thriller and felt the disappointment of an ending that doesn’t earn what came before it, this one does. The writing is meticulous, the lead performances are exceptional, and the show respects your intelligence from the first frame to the last.
Watch it. Then come back here and tell me whose fault you think it actually was.
