HBO's 'War' Premiered Last Night — Here's Our Verdict on the Divorce Drama

HBO has a new prestige obsession, and it arrived last night. War, the network's eight-episode legal anthology, premiered October 1 at 9pm ET — and if the early reviews are any indication, the fall TV season just got its first must-watch.

Created by George Kay, the series stars Dominic West as a billionaire tech mogul and Sienna Miller as a celebrated actress, locked in an explosive divorce that becomes a proxy battle between two rival law firms: Cathcarts & Sons versus Taylor & Byrne. Early reviews have been glowing, with review aggregators placing the series in the low-to-mid 80s — rarefied air for a debut.

A Divorce as Warfare

The premise is deceptively simple: two powerful people, one broken marriage, unlimited resources. But War uses the divorce as a lens for everything — wealth, fame, gender, power, and the legal machinery that turns private pain into public spectacle. West's tech mogul and Miller's actress are written as genuine equals, which makes their collisions feel less like melodrama and more like mutually assured destruction.

West, coming off a career of playing charmingly compromised men, finds arguably his richest role here — a character whose genius and cruelty are inseparable. Miller matches him beat for beat, and critics have singled out their scenes together as the series' crackling core. This is a two-hander in the truest sense, and both actors are operating at full power.

The Anthology Play

The anthology format is the show's smartest structural bet. Each season tells a self-contained legal story, which means War can attract top-tier talent without demanding multi-year commitments — the True Detective model applied to the courtroom. And HBO is already confident: a second season, built around a Marisa Tomei-led defamation storyline, is already in production.

Episodes will air weekly through November 19, giving the series room to build the kind of watercooler momentum that binge drops rarely achieve. In an era of disposable streaming content, appointment television still works — when the show earns it.

War has earned it. The verdict after night one: HBO's newest drama is the real thing, and the next seven weeks should be appointment viewing.

Kay's involvement is another reason for confidence. The creator has a proven feel for propulsive, high-stakes storytelling, and the legal-anthology format plays directly to his strengths — intricate plotting, moral ambiguity, and characters operating under extreme pressure. Combined with HBO's track record of letting prestige dramas breathe, War has every ingredient it needs. After last night's premiere, it looks like the network has another winner.
