Five long years after the last Charlie Kaufman film (and 12 even longer years since his last live-action effort), the celebrated screenwriter-turned-director is finally back with another cerebrally twisted tale of existential dread. Adapted from the Iain Reid novel of the same name, I’m Thinking of Ending Things takes viewers on a strange and squirmy journey full of psychological thrills that entangle time, memory, and experience into one bleak and nightmarish reality.
