Slow Horses Season Six Review: Spy Thriller Loses Comic Edge

Slow Horses season six represents a notable shift for the espionage thriller, being the first season not guided by its creator, Will Smith. Smith's previous work on "The Thick of It" and "Veep" contributed to the show's unusually sharp comic tongue, a quality that is described as discernible in the more straight-faced new story of season six. Beyond the absence of Smith's specific brand of drollery, the review points to a broader challenge: the natural erosion of creative works over time, suggesting that "Slow Horses" is now "old." The series centers on the staff of Slough House, a purgatorial division of MI5 where misfits and screw-ups are relegated to mundane tasks rather than being dismissed. These characters, despite their perceived incompetence and often shambolic nature, frequently outperform supposedly elite spies. River Cartwright, portrayed by Jack Lowden, is highlighted as a lead field agent who possesses the conventional good looks and some of the skills of a spy hero, yet is also characterized as brittle, luckless, and prone to whining. He often requires rescue from perilous situations. The review posits that the show's humor has been instrumental in allowing audiences to suspend disbelief regarding the survival of characters like River, who might otherwise be expected to succumb to fatal dangers. The series' distinctive approach of transplanting traditional spy thrills into decaying urban environments is still considered a refreshing element. However, the reviewer states that the enjoyment derived from this narrative "conjuring trick" becomes progressively more difficult with each passing year, indicating a diminishing impact of the show's established formula. The review implies that the show's reliance on its unique premise and comedic elements to overcome plot contrivances is becoming less effective as the series matures. The slickness and confidence in execution remain, but the underlying creative spark and the ability to surprise or consistently engage are perceived to be waning. This assessment suggests a potential creative plateau or a need for significant reinvention to recapture the show's initial appeal and critical reception. The review does not offer specific plot details but focuses on the overarching thematic and tonal shifts impacting the series' overall quality and viewer experience. The absence of creator Will Smith is presented as a key factor in this evolution, alongside the inherent challenges of maintaining creative momentum in a long-running series.
