I, Daniel Blake is a film of devastating emotional impact

You very much know what you are going to get from Ken Loach. He rarely works in genre, unless you consider the Loach picture a genre in itself (the case can be made). Since making Kathy Come Home for the BBC’s Wednesday Play strand in 1966 Loach has spent the ensuing 50 years making socially conscious, usually contemporary dramas with socialist themes. His films take place in working class milieus, and he finds warmth and humour even in the grimmest of subjects.
