Teit (Mikkel Boe Følsgaard) and Stine (Marie Bach Hansen) are storytellers who’ve left civilization to live off the land for a year – and podcast about the experience – in Superposition. The issue is that might not be the only Teit and Stine out there. This dense and well-constructed metaphysical thriller is designed to screw with your head, with splashes of heady sci-fi creepers like Coherence, Good Night Mommy, and The Night House spliced throughout to create an unnerving exercise in existential dread and doppelgänger distress. Though impressively economic and “small” in scope, Superposition feels expansive by virtue of its big ideas and Karoline Lyngbye’s staggering, inventive direction. She ratchets up the tension and pokes at philosophical quagmires, like the meaning of fidelity in bold, metaphysical ways. It all begs the question: if you met an exact copy of yourself, would you rather fuck, marry, or kill them? (B+)
