Sweetpea - Season 1 Apr 2026

The series’ sharpest narrative weapon, however, is its use of dark comedy and self-awareness. Rhiannon narrates her life as if it were a chic, violent daydream, and she maintains a meticulous diary filled with lists of people who have wronged her. This metafictional layer allows Sweetpea to interrogate its own premise. Is Rhiannon a feminist icon tearing down a patriarchal system, or is she just a deeply damaged woman commodifying her own trauma for a sense of agency? The show refuses to give a simple answer. Her burgeoning relationship with a kind, earnest journalist, AJ (Calum Lynch), who genuinely seems to see her, creates agonizing tension. Every warm, human moment between them is immediately undercut by the knowledge of the monster hiding in her wardrobe. The series asks a provocative question: can a person who has been systematically erased ever truly reintegrate into a world that refused to acknowledge her pain in the first place?

The genius of Sweetpea begins with its protagonist, Rhiannon Lewis (played with ferocious, brittle brilliance by Ella Purnell). On the surface, Rhiannon is a ghost. She is the “sweetpea” of the title—unassuming, overlooked, and painfully polite. By day, she toils as a junior reporter in a local British newspaper, an industry in decay, where her ideas are stolen, her name is misspelled on her mug, and her existence is met with casual, grinding condescension. At home, she cares for her dying father while enduring the casual cruelties of her popular, successful sister. The series’ first act is a masterclass in building a pressure cooker of micro-aggressions. Rhiannon is not a victim of grand, cinematic trauma; she is a victim of a thousand small cuts: the colleague who interrupts her, the stranger who dismisses her, the world that looks through her as if she were made of glass. Sweetpea - Season 1

In conclusion, Season 1 of Sweetpea is a far more complex and unsettling work than its “quirky serial killer” marketing might suggest. It is a character study as sharp as the blade Rhiannon wields, dissecting the corrosive nature of invisibility in a world that worships visibility. Ella Purnell delivers a transformative performance, capturing the heartbreaking vulnerability of a woman who just wants to be remembered, even if it’s for the wrong reasons. The season does not excuse Rhiannon’s actions, nor does it entirely condemn them. Instead, it holds up a distorted mirror to the audience, forcing us to confront our own complicity in the casual cruelties that create such monsters. By the final frame, we are left not with a sense of justice or closure, but with the lingering, uncomfortable question: How many sweetpeas are walking among us, silently counting the cuts, and waiting for the permission they will never receive to finally roar? The series’ sharpest narrative weapon, however, is its

In an era saturated with prestige television antiheroes, from Walter White’s crystalline empire to Dexter Morgan’s moral code, the archetype has become almost predictable: a brilliant, usually male, figure uses violence to resolve the gnawing dissonance between their perceived potential and their societal station. Starz’s Sweetpea , based on the novels by C.J. Skuse, takes this familiar blueprint and injects it with a venomous, feminine, and deeply contemporary dose of reality. Season 1 of Sweetpea is not merely a story of a woman who becomes a serial killer; it is a meticulously crafted, darkly comic, and ultimately tragic exploration of invisible labor, suppressed rage, and the violent reclamation of a self that society has already deemed worthless. Is Rhiannon a feminist icon tearing down a

This profound alienation is the engine of the narrative. The show cleverly subverts the typical “she was pushed too far” trope by revealing that Rhiannon’s capacity for violence was always there, a latent, simmering fury. Her first kill—a would-be street attacker—is an act of desperate self-defense. But the subsequent killing, of a smug, arrogant man who had bullied her since childhood, is something else entirely: a cold, premeditated, and deeply satisfying act of cosmic revenge. It is here that Sweetpea departs from its predecessors. Unlike Dexter, who kills to satisfy an internal “dark passenger,” or Villanelle, who kills with psychopathic glee, Rhiannon kills to be seen . She seeks, in the most horrifying way possible, a solution to the existential crisis of being a nobody. The adrenaline and power she feels as she stands over her victim is not about bloodlust; it is about the intoxicating realization that, for one fleeting moment, she is the most important person in the room.

Where Sweetpea truly excels is in its critique of the true-crime industrial complex. As Rhiannon’s kills escalate, the fictional town becomes enthralled by the mysterious “Epsom Downs Killer.” A handsome, opportunistic detective arrives, and the media transforms the brutality into a salacious puzzle. Rhiannon, the ultimate outsider, finds herself at the center of a narrative she never could have accessed in her real life. The show brilliantly posits that society is often more comfortable engaging with a woman’s violence as a spectacle—a thrilling aberration—than with the mundane, structural misogyny that might have precipitated it. Rhiannon’s final, chilling monologue of the season isn’t a confession; it’s a manifesto of ownership. She has stopped being the victim of her own story and become its sole, terrifying author.
