All Her Fault is a mystery-thriller series starring Sarah Snook, Jay Ellis, Jake Lacy, and Dakota Fanning. Based on Andrea Mara’s 2021 novel of the same name, the series premiered on Peacock on November 6, 2025, and consists of eight episodes.
The series follows Marissa Irvine (Sarah Snook), who arrives at a house to pick up her son, Milo, from a playdate with a classmate named Jacob Kaminski. However, the woman who answers the door insists she is not a nanny and that there are no children in the home. After contacting Jacob’s mother, Jenny (Dakota Fanning), Marissa learns that Jenny never sent any text messages arranging a playdate or pickup. Panicked, Marissa rushes home to meet her husband, his two siblings, and her business partner as they all gather to figure out what has happened.
This series felt more like a daytime soap opera and didn’t need to span a full eight episodes. By the fourth episode, it shifts into a collection of irrelevant side stories and events that add little to the main plot. Many scenes are stretched unnecessarily and end up filling time rather than advancing the story. While I can appreciate the attempt at a detailed narrative, the show would have been more effective as a three-, or at most four-part series.
The cast overall did a good job, including the supporting actors, though some of the dialogue between characters feels illogical, hard to follow, and occasionally over the top. Additionally, there’s very little chemistry between Sarah and her on-screen husband, their reactions and emotions toward each other come across as artificial and not at all reflective of how a couple might respond when their child goes missing.
Nevertheless, it’s still a series worth watching, especially if you have some downtime during the holiday season.
