2010 - 2019

Luther ran on BBC One from 2010 to 2019 across five series and twenty episodes, then came back once more in 2023 with the Netflix feature Luther: The Fallen Sun. Created by Neil Cross, it is the show that made Idris Elba a household name in Britain and a global leading man. The premise is simple and the execution is anything but.
DCI John Luther is a Metropolitan Police detective in London's Serious Crime Unit. He is brilliant at reading killers because he thinks a bit too much like one. He breaks rules. He leans on suspects in ways the Police Federation would not sign off on. His marriage is collapsing in the pilot and his career is a series of controlled detonations. The show pitches him against a new antagonist every story arc, usually someone whose crimes are designed to test not just his tradecraft but his self-control.
If you come to it expecting a standard procedural, you will be surprised by how quickly it tips into something stranger. The cases are often lurid. The London it shows you is a gothic version of the city, all tower blocks at dusk and empty warehouses and East End terraces. And there is the coat. The long, heavy, dark camel coat that Elba wears in almost every scene. The coat is the show's visual signature and the closest thing TV has produced to a modern Sherlock silhouette.
Idris Elba is the engine. Full stop. He plays Luther with a physicality that no other British detective lead on television has matched in the last fifteen years. Big, quiet, thinking. You can see him working a suspect before he says a word. When he loses his temper the scene actually lands because he spends the rest of the time holding it in. It is a performance built on what he does not do. Elba had already shown what he could do as Stringer Bell in The Wire, but Luther gave him a lead who carried every scene.
Across from him is Ruth Wilson as Alice Morgan, and this is the piece of casting that lifts the whole series. Alice is a physicist with a genius IQ and absolutely no moral brakes. She is introduced as a suspect in the pilot and then becomes something much harder to categorise. Wilson plays her as fascinated rather than cruel. She watches Luther like a specimen she is curious about. Their scenes together are the best thing the show has to offer, and both actors know it.
Around those two, the ensemble rotates as the series evolves. The core partners and superiors over the run:

That is a serious supporting bench. Every series has at least one memorable guest antagonist, and the show takes its villains seriously. They are written with actual psychology, not paper cut-outs.
On the surface Luther is a police procedural about a man who catches very bad people. Under the surface it is about whether the man catching them is meaningfully different from them. Neil Cross writes Luther as someone who can see the shape of a violent mind because he recognises its contours. The suspense in any given episode is less about will-he-catch-them and more about will-he-stay-on-his-side-of-the-line.
The relationship with Alice is the thesis of the whole show. She is what happens when a clever person throws away the rulebook. Luther is what happens when a clever person keeps the rulebook but questions every page. The friction between those two positions is the thing the series keeps worrying at, season after season.
It is also a show about institutions. Luther's bosses are not cartoon bureaucrats. They are people trying to do police work within rules that occasionally collide with the worst of humanity. His trouble is not that he disrespects the Met. His trouble is that he respects it and still does what he does.
The London of Luther is its own character. Director Sam Miller and the team who shot the early series cast the city as a gothic place. Rain on empty streets at three in the morning. Fluorescent-lit interview rooms. Bleak flats where something terrible has happened and you can feel it in the walls before the camera shows you anything.
The show has a palette. Blacks and browns and dirty amber. The interiors are warm and claustrophobic. The exteriors are cold and wide. And the coat. The coat ties every scene together, a walking silhouette that reads from a hundred yards away. Cinematographers working on British crime drama have cited the Luther look for years. You can feel its influence on later shows in the genre, from Slow Horses to The Night Of.
Elba was nominated for BAFTAs and Emmys for the role and won a Golden Globe for it in 2012. Critical reception was broadly enthusiastic for the first two series, with views cooling slightly on series 3 and 4 before series 5 and the film reignited interest. The show was a breakout hit for the BBC and is one of the reasons Elba became a Bond conversation for the rest of the decade.
The Luther that people loved was the Luther of series 1 and 2. Focused, controlled, psychologically claustrophobic. The later run is more spectacle and less intimacy.
It left a genuine footprint. British crime drama after Luther is noticeably more willing to be stylish, to commit to a gothic palette, to push a lead detective into morally dangerous territory. Shows like Mare of Easttown and True Detective are working in a tradition that Luther helped shape, even if they were made in very different places.
Because of Elba. That is the short version. You can write a long analysis of Cross's scripts or the show's visual identity or the villain-of-the-season structure, but the honest answer is that Luther works because Idris Elba, in his camel coat, with a briefcase and a ruined marriage and a physicist who might be in love with him, is the most watchable British TV lead of his generation.
Series 1 and 2 are near-perfect. The middle of the run wobbles. The later run steadies. The film is a bigger, pulpier version of what the show always was. If you have never seen it, start at series 1 and watch Elba put a character on the map. That is the job.
