A very classy thriller indeed: C4’s The Undeclared War reviewed

The Undeclared War has many of the traditional signifiers of a classy thriller: the assiduous letter-by-letter captioning of every location; the weirdly precise time-checks (‘Sunday 09.47’); above all, the frankly baffling opening scene. In it, a young woman walked around a deserted fairground, broke into a beach hut that turned into a gym and spotted a door in the ceiling which led into a stately home.

Gradually, the fact that the first episode interspersed this with the same woman typing computer code made it clear what was going on: writer/director Peter Kosminsky was making a plucky attempt to solve his main challenge here. Never afraid of a big issue, Kosminsky has previously tackled the invasion of Iraq (The Government Inspector), British Isis volunteers (The State) and the postwar history of Palestine (The Promise). Now he takes on cyber warfare, which has the rare property of being both terrifying and undramatic, with much of the action consisting of people doing advanced computer science.
