“It’s like we’ve forgotten who we are,” the hero of Interstellar complains. “Explorers, pioneers, not caretakers … We’re not meant to save the world. We’re meant to leave it.” It could be the epigraph of our age.
Don’t get me wrong. Interstellar is a magnificent film, true to the richest traditions of science fiction, visually and auditorally astounding. See past the necessary silliness and you will find a moving exploration of parenthood, separation and ageing. It is also a classic exposition of two of the great themes of our age: technological optimism and political defeatism.
