Morris Yang’s review published on Letterboxd:
There’s nothing quite like this one. Kaufman at his most unrestrained, unconscious, unsettling: a Lynchian tapestry of all the unease that comes with existing, alone or with another — or both at once. The recesses go deeper, time seems to distillate into a synchronic eternal, compartments unfold and box themselves into storage spaces in the mental warehouses and psychological manifolds of an always-already societal symbiosis: of relationships, interactions, hierarchies, memories, co-habitating spaces and minutes. I’m Thinking of Ending Things synthesises the sprawling inventions of Synecdoche, New York and the impossible intimacies of Anomalisa, and then reinvents it some: into a pure existential horror whose modus operandi rests within the duality of past traumas and future threats of mediocrity and emptiness. (Hereditary can only dream of such function to match its form.) One of the definitive horror films of this century, alongside Mulholland Drive, and likely 2020’s best.
