War Season 1 Review: HBO’s New Legal Drama Turns Divorce Into a Battle for Power

When two immensely wealthy people decide to divorce, money should make almost every problem easier to solve. In War, it does the opposite. Their separation becomes the spark for a vicious contest between two rival London law firms, where professional ambition, personal grudges and carefully guarded secrets turn a divorce into a battle for control.

Led by Dominic West and Sienna Miller, HBO and Sky’s eight-part legal drama follows tech entrepreneur Morgan Henderson and international film star Carla Duval as their marriage collapses in full public view. But the deeper the legal teams become involved, the less the case resembles a straightforward separation.

Created by George Kay, who serves as lead writer and executive producer, War arrives with a clear understanding of what makes legal dramas compelling: sharp conflicts, complicated relationships and characters who are often willing to cross uncomfortable lines to get what they want.

The series has already been ordered for two seasons and is designed as an anthology, with each season telling a separate legal story and introducing a new central cast. For its first chapter, that format gives War plenty of room to tell Morgan and Carla’s story without overstaying its welcome.

A Divorce Becomes a Fight Between Two Powerful Law Firms

Morgan and Carla’s divorce quickly draws Cathcarts & Sons and Taylor & Byrne into opposing corners.

The two firms already have a history of hostility, and their rivalry soon becomes almost as important as the breakdown of the marriage itself. Lawyers on both sides begin searching for weaknesses, exploiting private information and turning every development into another opportunity to gain an advantage.

That is where War finds much of its energy.

The series leans into the less flattering image of the legal profession: ambition, manipulation, greed and an obsessive desire to win. Its lawyers regularly make questionable choices, sometimes treating their own clients and colleagues as pieces in a much larger game.

Yet their behavior is also what makes the drama so entertaining. Watching two groups of highly capable professionals continually attempt to outmaneuver one another creates tension even when nobody is physically in danger.

Morgan and Carla are wealthy enough that a conventional divorce settlement is unlikely to threaten their ability to live comfortably. What is really at stake is pride, reputation and control.

The series gradually reveals what each side knows and, more importantly, what they are prepared to do with that knowledge.

A Legal Drama With a Shakespearean Streak

At its center, War is still a story about a marriage that has gone badly wrong.

Carla captures the emotional contradiction at the heart of the series when she reflects:

“I don’t understand how you can start so in love and end up so stuck, so humiliated, so determined to ruin each other.”

That question gives the drama much of its emotional weight.

Morgan and Carla are not simply fighting over the practical consequences of their separation. Their hurt has become intertwined with the legal battle, allowing the lawyers to transform personal resentment into professional ammunition.

The structure occasionally recalls Damages, particularly in the way the story moves between opposing legal teams and the people caught between them. At the same time, War grounds its heightened drama with more ordinary details of legal work, from document exchanges to junior lawyers struggling to keep up with increasingly complicated demands.

Then the series pushes those relatively mundane proceedings toward melodrama.

The rivalry between Cathcarts & Sons and Taylor & Byrne means even small developments can become significant. Paparazzi add pressure, personal weaknesses become weapons and every new piece of information potentially changes the balance between the two sides.

That constant movement keeps the season difficult to predict.

Dominic West and Sienna Miller Anchor the Series

The central performances are one of War‘s strongest assets.

Dominic West and Sienna Miller give Morgan and Carla enough complexity to avoid reducing them to a simple hero-and-villain dynamic. Both are wounded by the collapse of their relationship, and both respond in ways that cause further damage.

Their actions can be unpleasant, but the performances maintain the sense that these are deeply hurt people rather than characters who can be easily categorized.

The supporting cast also adds considerable depth.

Archie Renaux is particularly effective as Johnny Warren, a young lawyer who becomes increasingly immersed in the aggressive culture surrounding the two firms. His position offers viewers a less established perspective on the profession as he discovers just how far the people around him are willing to go.

Rose Williams has a smaller role and does not appear in even half of the season’s episodes, but she makes an impression when she does appear.

Two performances feel somewhat less convincing by comparison: Aran Murphy as Gabe Duval and Shaheen Jafargholi as Saeed Masood. Neither is necessarily poor, but their performances feel slightly less natural alongside an otherwise strong ensemble.

The actors playing the lawyers, meanwhile, understand exactly how entertaining unpleasant people can be. Many of the show’s legal professionals make terrible decisions and treat one another badly, but the cast gives those confrontations enough personality to keep them engaging.

The Relationships Behind the Legal Battle

The chemistry between the cast helps War work beyond its central legal conflict.

West and Miller make Morgan and Carla’s complicated history convincing, allowing affection and resentment to coexist within the same relationship.

A similarly layered dynamic emerges between Phoebe Fox and James McArdle, who play Serena Byrne and Nicholas Taylor. The pair are married as well as professional partners, and they are attempting to keep Taylor & Byrne running while preparing for the arrival of a baby.

Their relationship carries the tension of a long-term partnership under pressure. There is genuine affection between them, but accumulated frustrations and resentment are increasingly difficult to ignore.

McArdle also has strong chemistry with Pip Torrens, whose character shares a history with him as a former colleague. That backstory gives the hostility between the two firms an additional personal dimension.

These relationships prevent War from becoming simply a succession of legal maneuvers. The professional battles matter because they are constantly colliding with marriages, friendships and loyalties that are already under strain.

The Drama Is Not Afraid of Cruelty

At times, War pushes its characters into deliberately uncomfortable territory.

Two scenes stand out. In one, a character intentionally worsens another person’s speech impediment. In another, a child becomes a pawn in the ongoing divorce battle.

Neither moment is presented as admirable. Instead, the performances underline how cruel and disturbing the characters’ behavior has become.

That distinction is important because the series spends much of its runtime following people who manipulate and undermine one another. Their methods may drive the story, but War does not appear to celebrate them.

Instead, their willingness to cross ethical boundaries becomes another source of suspense.

Why the Eight-Episode Format Works

The first season consists of eight episodes, and that length proves well suited to the story.

A six-episode season might have forced the conflict to move too quickly, while ten episodes could have created more opportunities for unnecessary detours. Here, only a small number of scenes feel as though they could have been removed without significantly affecting the overall narrative.

More importantly, the season is able to reach its conclusion without leaving a collection of unresolved questions simply to keep the story alive.

That is particularly useful given the anthology format.

Morgan and Carla’s story does not need to continue indefinitely. Instead, War can leave them behind and move into an entirely new legal conflict.

The second season is already included in the show’s two-season order and is now in production. Marisa Tomei, Kelly Macdonald and David Harewood will lead the next installment, which will center on an explosive defamation case.

That gives George Kay the opportunity to completely change the characters and circumstances while retaining the show’s central interest in power, conflict and the law.

It also means the second season will have to establish its own identity rather than simply continuing the momentum of the first.

A Promising Beginning for HBO and Sky’s Legal Anthology

War takes a familiar television setup — wealthy people using lawyers to fight over the remains of a relationship — and gives it enough pace, tension and personal hostility to feel engaging.

The central divorce is surrounded by money, fame and publicity, while the feud between the two law firms turns almost every development into another round of a much older battle.

The drama occasionally ventures into uncomfortable territory, and a couple of supporting performances are less convincing than the rest of the ensemble. But those issues do little to undermine the season’s strongest qualities.

West and Miller provide a compelling emotional center, while Fox, McArdle, Torrens, Renaux and the wider cast bring energy to a legal world populated by ambitious people constantly testing how far they can go.

Most importantly, the first season knows when to end.

Eight episodes give Morgan and Carla’s story enough space to develop without exhausting the premise, while the anthology structure leaves the series free to explore a completely different case next time.

War Season 1 premieres on October 1, 2026, on HBO and HBO Max, followed by its UK launch on October 2 on Sky and NOW. New episodes will be released weekly.

With a new defamation case already planned for Season 2, the series has established a format that can move from one high-stakes legal battle to another while continually introducing new characters, rivalries and reasons to take sides.
