What About Slow Horse Seasons 1 and 2?

So far, we’ve talked about slow horse season 3. Now let’s learn about the previous 2 seasons. 

Overview of Slow Horse Season 1

Based on the book of the same name, Slow Horses starts steadily and finishes its six-episode run on a high note. Billed as a “darkly funny espionage drama,” the series brings together a group of misfit characters who embark on a single case that unravels the dark underbelly of London. While the premise may not be particularly imaginative, the execution proves to be effective.

The story follows River Cartwright, an MI5 agent whose early operation goes disastrously wrong, resulting in his demotion to Slough House, a dead-end for agents who have made career-ending mistakes. There, he encounters the enigmatic and no-nonsense Jackson Lamb. Teaming up with other rejected agents and unconventional individuals, they become entangled in a high-stakes mission involving the terrorist group, the Sons of Albion.

The Sons of Albion aim to “keep Britain British” and have kidnapped a British Muslim named Hassan Ahmed, threatening to behead him live on air. As time ticks away, Jackson clashes with the current MI5 leader, Diana Taverner, as they race to locate the Sons of Albion before a failed operation and a public tragedy escalate into potential warfare.

While the setup is straightforward, the writers of Slow Horses keep the twists and surprises flowing until the finale. The first season concludes with a revealing moment that adds depth to one of the characters haunted by their past, leaving viewers intrigued.

The strength of the show lies in its ensemble cast, led by the exceptional performances of Gary Oldman as Jackson Lamb and Jack Lowden as River Cartwright, who brings a mix of charm and charisma to his role. The supporting characters also leave their mark, creating a solid ensemble. Slow Horses is a reliable crime drama that captivates with its storytelling.

Admittedly, some contrivances and moments may strain credibility, and a few jokes fall flat. Episodes 4 and 5 introduce an extended cat-and-mouse game that could have benefited from tighter editing. Nevertheless, these minor issues do not overshadow the enthralling season finale that ties up loose ends.

Slow Horses successfully combines the expected elements of the genre in a compelling and well-written manner. Although it has flaws, the series leverages its ensemble cast and engaging story to make it one of the standout offerings on Apple TV+.

Overview of Slow Horse Season 2

Slow Horses Season 2 proves to be another darkly funny and decent adaptation, showcasing its stability and consistent quality amidst a turbulent year of streaming offerings. While the series is not flawless and has some narrative hiccups, it remains a solid and enjoyable watch. In its second season, Slow Horses feels more confident in its storytelling and presentation of ideas.

Spanning six episodes, Season 2 adapts the second novel in the Slow Horses series, Dead Lions, focusing on Russian sleeper agents known as Cicadas who have infiltrated British society. When former agent Richard Bough is discovered dead on a bus with the word “Cicada” on his phone, Jackson Lamb assembles his team to uncover the truth.

As the plot unfolds, various players enter the picture through interconnected subplots that intertwine with the main narrative. Min and Louisa handle security for a crucial meeting involving Russians, while River undertakes an undercover operation in the quiet village of Upshott to expose a sleeper agent. Meanwhile, Catherine and Lamb face their challenges in London.

While Slow Horses Season 2 may not be packed with action or thrilling chases, it compensates with tense sequences and clever twists. However, there are a few contrivances and an abrupt ending. Additionally, characters like Roddy Ho and Shirley are unfortunately underutilized, despite having intriguing storylines.

One notable aspect this time is the balance between dark humor and suspenseful moments. The series delivers genuinely funny scenes, with the ability to swiftly transition from somber and heartfelt to outright humor with a single line of dialogue. An amusing recurring joke involves Jackson Lamb eating different foods in each scene, referencing his messy eating habits with noodles in the first episode.

Considering everything, Slow Horses Season 2 is an enjoyable and solid continuation worth exploring for fans of the first season. The improved balance between humor and drama represents a step forward, although a few narrative issues prevent it from becoming an even more robust offering. Nonetheless, the series demonstrates the consistent effort that solidifies its position as one of Apple’s dependable shows.
