Slow Horses Season 4

What BollyAI Thinks

Season 4 returned to near-unanimous acclaim, and by this point Apple TV+ was treating it as one of its flagship spy franchises. The show's sustained quality across four seasons - no score below 95%, two perfect seasons - is an achievement almost without parallel in modern streaming drama. The writing remained sharp, Oldman's performance grew rather than coasted, and the institutional plotting had become the show's own distinctive genre: British political thriller as slow-burn dark comedy.
