These supposedly “single take” films are either exhilarating or tedious. They’re prone to becoming more about the gimmick than the story, more about spotting the cuts than engaging with what’s happening. Thankfully this falls into the former category. There’s enough tension and release to keep the narrative moving forward. It’s helped 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.
