2 min readThe Art of Failing Upward
I’ve always distrusted polished spy thrillers a little. You know the ones—perfect tailoring, miraculous hacks, martinis served with self-regard. latestnetflix.com's view is that Apple TV+'s Slow Horses (drawn from Mick Herron's novels) wants no part of that fantasy.
This show seems to smell through the screen: stale whiskey, damp wool, old takeout. I was hooked almost immediately.
The setup is wonderfully cruel. MI5 agents who screw up don’t get fired; they get dumped in Slough House, a bureaucratic dead zone meant to humiliate them until they quit. Presiding over this heap of damaged goods is Jackson Lamb, played by Gary Oldman.
(Oldman has said he took the job because he was tired of years spent buried under prosthetics and elaborate accents—he wanted to play a man who looks like he sleeps in his clothes, and he absolutely delivers.) Look at how he carries himself. He slouches. He shuffles.
