For decades, the imagery of British espionage has swung between two founding myths: the glamorous, pyrotechnic fantasy of James Bond — dry martinis, impeccable Savile Row suits and missions in Riviera casinos — and the twilight, bureaucratic melancholy of the George Smiley universe brought to life by John le Carré. Slow Horses, the brilliant adaptation of Mick Herron’s novels steered by Will Smith (the British writer of Veep, not to be confused with the American actor) for Apple TV+, blows up both canons from the foundations to settle in a much grubbier, more honest and savagely funny territory: the administrative dumping ground.

Slough House is not a high-tech operations base in Regent’s Park; it’s a decrepit building near Farringdon station where MI5 exiles its “slow horses”, agents who have made an unforgivable mistake — leaving a classified briefcase on the Tube, failing a training exercise or messing up a press conference — but whom the service can’t legally fire. The purpose of this purgatory is to bore them into resigning amid mountains of dusty files and dead dossiers.

And at the head of this asylum of outcasts is Jackson Lamb, played by Gary Oldman in the most absolute and uninhibited state of grace of his recent career. Disheveled, greasy hair plastered to his forehead, holes in his socks, shirt stained with noodle sauce and an almost musical propensity for untimely flatulence, Lamb looks at first glance like a human wreck drowned in bargain whisky. But beneath that crust of neglect and calculated rudeness beats the mind of the Cold War’s deadliest and most lucid spy, a Berlin survivor who knows every lever of the state’s sewer.

Direction and mise-en-scène

The staging deliberately avoids the sterile sophistication of contemporary procedurals. The direction goes for a damp, grey, nicotine-stained atmosphere, captured by Eben Bolter’s cinematography with a texture that evokes the dirty grain of 1970s British crime cinema. You can smell the damp and the stale paper of Slough House through the screen; the fluorescent lights flicker with a sickly hum, and the cheap particleboard desks are crammed with overflowing ashtrays and cardboard boxes.

The visual contrast with MI5’s headquarters at Regent’s Park — “the Park”, dominated by armored glass, gleaming marble and the antiseptic overhead lighting commanded by Diana Taverner (Kristin Scott Thomas) — is not mere formal decoration but a political and moral statement: the cleaner the building, the dirtier and more cowardly the decisions made in its offices.

The pacing is another of its great triumphs. Far from the contemplative paralysis many prestige British productions fall into, Slow Horses structures its seasons in tight six-episode arcs where not a single minute is wasted. The chases and shootouts are resolved with a dry, chaotic realism where bullets hurt, guns jam and agents make human mistakes under the pressure of panic.

Performances and script

The ensemble works with the precision of a clock that has been broken on purpose. Jack Lowden delivers a superb River Cartwright: an impulsive, ambitious and frustrated agent, weighed down by the shadow of his grandfather (a legendary service veteran played masterfully by Jonathan Pryce) and determined to redeem himself whatever it takes. His dynamic with Oldman is pure gold, a constant crossfire in which River’s youthful naivety crashes against Lamb’s devastating cynicism.

Kristin Scott Thomas, for her part, nails a relentless, calculating and Machiavellian Diana Taverner, capable of betraying her subordinates with a smile of diplomatic courtesy while sipping coffee from a fine porcelain cup. The face-offs between Scott Thomas and Oldman on London park benches, chewing over reproaches and mutual extortion in low voices, are among the best moments of television dialogue of the decade.

Will Smith’s script keeps the caustic bite of Herron’s novels. Every insult Lamb spits at his charges — “If any of you were remotely competent, you wouldn’t be in this bloody room” — is both a defensive barrier and a savage survival pedagogy. Beneath the mountain of grime and contempt, Lamb is the only one who truly protects his slow horses when the Park’s top brass decide to use them as disposable scapegoats.

The best

• A stratospheric Gary Oldman: A colossal creation, funny, repulsive and lethally intelligent.
• Narrative economy: Six episodes per season, no fat, no filler and perfectly constructed plot twists.
• The cast’s acid chemistry: From Kristin Scott Thomas to Saskia Reeves and Christopher Chung, every character adds an essential shade to Slough House’s dysfunctional family.
• A perfect balance of black humor and suspense: It makes you laugh out loud a second before tightening your stomach with a cold-blooded execution.

The worst

• The premise can demand some suspension of disbelief: It’s almost miraculous that such an openly bungling team manages to dismantle state conspiracies time and again.
• Its deliberate visual roughness: Anyone looking for the stylized glamour or polish of traditional spy productions will find no comfort here.

The Claqueta Ácida Verdict 💀

Slow Horses is a glorious antidote to the pompous solemnity and papier-mâché patriotism of conventional spy cinema. A venomous, addictive and masterfully acted series that proves that when the system is rotten to the core, the only ones capable of saving the furniture are the ones the system had already thrown in the trash. Essential. 💀

In stark disagreement with the review given by Lúa Ácida.

“

La suciedad deliberada y el hedor a calcetín usado de Jackson Lamb pueden ser un placer culpable para los amantes del cinismo de taberna, pero no ocultan que los engranajes de la conspiración beben directamente de John le Carré sin inventar la rueda.
