Slow Horses: Season 5 ReviewA shooting in London marks the beginning of a prolonged assault on the city by mysterious forces. Can the Slow Horses figure out what’s going on — and who’s behind it? The computer savant played by Christopher Chung in spy show Slow Horses is, put simply, a thundering twat, a preening berk, cringe in human form. (“Nothing raises my Spidey-Senses as much as hearing a woman is happy to spend time with you,” splutters Gary Oldman’s unhygienic spymaster Jackson Lamb.) Ho’s implausible new love life turns out, of course, to be part of a bigger conspiracy, which unravels over six episodes packed with action, dry wit and, this being Slow Horses, the odd burst of Jackson Lamb flatulence.
