What could well be Ken Loach’s final film has as much fire and fury as his debut Poor Cow did in 1967, if we discount his pioneering TV work in the run-up. The visual style hasn’t changed a great deal in the years since, but that’s because the British movie veteran, soon to turn 87, isn’t much fussed about surfaces, it’s the inner lives of his characters that he wants to capture. In that respect, The Old Oak would make a fitting swansong, capping the recent North-East trilogy with a vital film that is clearly the work of the team behind previous Cannes Competition hits I, Daniel Blake and Sorry We Missed You.
