All Her Fault on Peacock Is Quietly Becoming One of TV’s Most Intense Psychological Thrillers
Peacock’s new limited series All Her Fault doesn’t waste time pulling viewers into its gripping psychological maze. Starring Sarah Snook, Dakota Fanning, and Jake Lacy, the show unfolds with a slow-burning intensity that feels both unsettling and deeply human. By the end of the second episode, it’s clear this isn’t just another crime drama, it’s a thought-provoking examination of grief, guilt, and the fragile state of the mind under unimaginable pressure.
From the very beginning, the acting sets the tone. Sarah Snook delivers a haunting performance as a mother unraveling in real time, her emotional state intricately tied to her missing son, Milo (played by Duke McCloud). Snook captures the rawness of maternal fear and psychological exhaustion with an honesty that makes every scene feel uncomfortably real. Her portrayal of mental health under crisis isn’t sensationalized, it’s lived-in, messy, and deeply affecting.
The drama escalates with the introduction of Sophia Lillis, whose character is both mesmerizing and deeply disturbing. Lillis brings a chilling unpredictability to the role, seamlessly shifting between personalities, disguises, and calculated behavior. Her sneaky, conniving presence keeps viewers constantly questioning motives and truths. As the story progresses, it becomes clear that her involvement in Milo’s disappearance is far more complex, and dangerous, than initially suggested.
By episode three (of eight), the series sharpens its focus. Tensions rise as cracks form between characters, including a brief but telling altercation that fuels speculation around a possible accomplice. While Jay Ellis appears as a colleague to Snook’s character, a financial professional who publicly advocates for Milo and even helps organize search efforts, his role invites quiet suspicion. The show cleverly plays with audience perception, allowing theories to breathe before delivering its reveals.
Without giving too much away, the series does confirm that the true accomplice is Dominic Masterson’s character, Kyle, adding another layer of betrayal and shock to the narrative. The way this revelation unfolds is measured, deliberate, and emotionally resonant, never rushed, never cheap.
Anchoring the investigation is Michael Peña, whose detective work grounds the series in realism. Peña’s performance is steady and intelligent, offering a calm counterbalance to the emotional chaos surrounding the case. His scenes add credibility and tension, reinforcing that this story isn’t just about what happened, but how truth is uncovered, piece by painful piece.
All Her Fault thrives on anticipation. It trusts its audience, revealing just enough to keep you hooked while holding back the full picture. The result is a series that’s intense without being overwhelming, dramatic without being melodramatic, and psychologically rich without overexplaining itself.
If the first three episodes are any indication, Peacock has a standout thriller on its hands, one that lingers long after the screen goes dark.
