All Her Fault, the new Prime Video miniseries, topped the platform’s viewership charts right from its premiere in January 2026. Starring Sarah Snook in the lead role, the production adapts the novel by Irish author Andrea Mara and delves into a crime involving a wealthy Chicago family. The plot, which has already received two Golden Globe nominations, follows the successful recipe of thrillers like “Big Little Lies,” attracting the Brazilian audience with its mysteries and family dramas.
The storyline follows Marissa Irvine, a wealth manager played by Snook, who panics when she goes to pick up her 5-year-old son from a friend’s house and discovers he was never there. Due to this disappearance, the investigation expands, revealing hidden secrets and conflicts among the characters. With eight episodes available, the series maintains suspense until the end, despite a sometimes slow pace, and stands out for the protagonist’s convincing performance.
Star-Studded Cast and Intense Themes
In addition to Sarah Snook, who plays the ambitious Shiv Roy in “Succession,” the cast includes Dakota Fanning as Jenny Kaminski, a working mother who blames herself for what happened, and Michael Peña as Detective Alcaras, involved in an ethical dilemma. The villain Carrie Finch, played by Sophia Lillis, is the nanny behind the kidnapping, in a clear reference to the classic “The Hand That Rocks the Cradle.” Meanwhile, the Irvine family conflicts take center stage, exploring issues such as loyalty, guilt, and privilege, all set against the imposing backdrops of Chicago, filmed in Australia.
Despite comparisons to “Big Little Lies,” the miniseries does not reach the same depth in social critique but compensates with well-constructed suspense. Thus, for fans of psychological thrillers, “All Her Fault” offers an engaging marathon, mainly thanks to Snook’s performance. Therefore, if you’re looking for a new series to binge-watch on streaming, this could be a sure bet for your January nights.
