This is about as existential as filmmaking gets, as scientists, historians and theologians try to convey a message of warning to future generations 100,000 years into the future, the life of the decaying uranium, not to attempt any kind of excavation into the underground metropolis that houses the fire within. The film intercuts various boffiny talking heads, determined yet completely humbled by the magnitude of the task before them, with dreamlike dollyed shots of Onkalo, the waste repository itself, a vast concrete leviathan hewn from the Earth’s bedrock.
It’s a little shocking and beggars belief that countries like the US (top of the list with 105 power-plants) have no solution in place for the long-term storage of spent nuclear fuel. But this is far from an evangelical cry for us humans to change our ways, in fact in many ways the message seems to be that current humanity is but a mere speck on the grand canvas of our planet’s future history. Haunting and quite, quite unforgettable.
