There is something sharp, exciting and more original tucked within "The Berlin File" - and it is in moments a sleek, crackling film - but it all feels somehow misshapen.

As soon as "The Berlin File" takes flight with its exhilarating action set pieces, memories of any muddles evaporate amid the tension and vivid engagement with settings, from courtyards to fields.

The Berlin File benefits from gritty surroundings that add a cold war realism to this otherwise confusing tale of conflicted loyalties and secret agendas.

A highly underrated thriller from South Korea set in the German city of Berlin, off all places.
