Prime Video’s Girlfriend, the six-part psychological thriller that premiered on September 26, 2025, has left viewers reeling, with social media flooded by confessions of all-nighters and sleepless nights. Starring Line of Duty breakout Olivia Cooke as the enigmatic Lauren and Robin Wright as her domineering mother Vivian, the series transforms a seemingly idyllic family dynamic into a labyrinth of deceit, manipulation, and shocking revelations. What begins as a tale of a young woman returning home for a wedding spirals into a harrowing game of psychological warfare, where every conversation hides a dagger and every hug conceals a lie. Fans on X (#GirlfriendPrime) are obsessed, dubbing it “edge-of-your-seat addictive” and “the best thriller of 2025 so far,” with one user tweeting, “Binged all six episodes in one sitting—a crazy ride I couldn’t stop!”

Lauren, a 28-year-old graphic designer escaping a toxic breakup, arrives at her family’s sprawling Connecticut estate for Vivian’s remarriage, only to uncover buried traumas and Vivian’s suffocating control. Cooke’s Lauren is a masterclass in quiet unraveling—her wide-eyed vulnerability masking a simmering rage—while Wright’s Vivian is a chilling matriarch, her warmth laced with venom. The duo’s chemistry is electric, from tense dinner-table stares to a midnight confrontation that’ll have you gasping. Supporting turns from Jonathan Bailey as Lauren’s charming but suspicious brother and Phoebe Dynevor as her estranged best friend add layers of intrigue, with director Nona Khodai’s taut pacing ensuring no moment breathes easy.

Adapted from a 2019 novel by Emma Cline, Girlfriend explores the suffocating bonds of family and the cost of silence, earning a 94% on Rotten Tomatoes for its “gripping psychological depth.” Critics praise Cooke’s “career-defining” performance, with The Guardian calling it “Succession meets Gone Girl in suburbia.” Fans admit the finale’s twist “ruined my sleep,” bingeing despite the dread. Streaming to Prime Video’s Top 5 globally, Girlfriend is the must-watch that’s already crowning 2025’s thriller throne. Will Lauren break free, or will Vivian’s grip prove fatal? Dive in—but don’t say we didn’t warn you about the all-nighter.
