These real time, supposedly “single take” films are either exhilarating or tedious. Unfortunately they become more about the gimmick than the story. More about spotting the cuts than engaging with what’s happening. This falls into the former rather than the latter category. There’s enough tension and release to keep the narrative moving forward. It’s helped in no short part by some spectacular cinematography. From mud to farm, crumbling tunnels to burning city, the mood and energy changes with emotional tension of the story. Worth the two hours the freight train takes you down the tracks.
