The Evolution of the Modern Spy Thriller
The landscape of espionage television is shifting toward a more grounded, high-stakes realism. The benchmark for this shift is often seen in the success of Slow Horses, a series that has set a high bar for the genre.
Current trends show a growing appetite for adaptations of bestselling novels, such as the work of Tom Bradby. These stories often move away from idealized agents, focusing instead on complex geopolitical plots involving Russian assets and senior politicians, as seen in Secret Service.
The Rise of the “Anti-Hero” Agent
Rather than invincible spies, audiences are gravitating toward characters who face internal and external pressures. This trend emphasizes the “arms race” of spying, where the tension comes from political vulnerability and the risk of infiltration.
The Novel Wave of Mystery and Whodunnits
The traditional murder mystery is being reimagined through the lens of surrealism and historical art. We are seeing a move toward “clever” narratives that blend high culture with crime.

A prime example is Here’s Not a Murder Mystery, which utilizes a 1930s setting and the world of surrealist artists, including René Magritte, to create a puzzling plot. This suggests a trend where the setting is as much a character as the detective.
Psychological Depth in Action Thrillers
Action-oriented series are increasingly incorporating deep psychological explorations. The focus is shifting from the spectacle of the fight to the trauma of the fighter.
In Man on Fire, the narrative centers on John Creasy, a former Special Forces soldier. The plot doesn’t just rely on his skills in surviving desolate situations but focuses on his battle with PTSD and his path to redemption through the rescue of a kidnapped girl.
Similarly, thrillers like Prisoner heighten tension by trapping characters in high-pressure environments—such as a race against time following a brutal ambush—forcing an unlikely alliance between a transport officer and a high-value inmate.
Humanizing the Medical Drama
There is a noticeable trend toward “relatable” medical content. While prestige dramas once dominated, there is a rise in medical sitcoms that highlight the reality of the healthcare system.
St. Denis Medical exemplifies this by focusing on overworked staff in an underfunded Oregon hospital. By blending humor with emotional beats, these shows mirror the real-life frustrations and resilience of medical professionals, moving away from the idealized versions of hospital life.
The Global Influence of Crime Noir
Overseas crime dramas continue to hold a strong grip on viewers, particularly those that blend professional investigation with personal tragedy. The “Nordic” style of crime remains a powerhouse in streaming.

Series like Nordic Murders demonstrate a trend toward complex character arcs, such as a former district prosecutor who has served time in prison for murder, only to return to the right side of the law. This adds a layer of moral ambiguity that keeps audiences engaged.
