‘Slow Horses’ is thriller television at its best
It may come as a surprise to anyone who has read Mick Herron’s peerless Slough House novels, but Slow Horses, Apple TV’s high-profile adaptation of the first book in the series, is not funny. Instead, it takes Herron’s uproariously comic premise — that a group of misfit British spies, cast out of MI5 for misdemeanors exaggerated and accurate alike, have been reduced to grubbing about in a grim office on the periphery of the City of London — and plays it almost entirely straight. Gone are the laugh-out-loud one-liners and endearingly witty pieces of throwaway badinage. Instead, we have a big-budget spy thriller, polished and scripted to within an inch of its life. It’s a bit like seeing the Fresh Prince of Bel-Air reinvented as a gritty urban drama.
