Kiyoshi Kurosawa’s Pulse presents the internet as a path for unsettled spirits, resulting in a horror film that develops gradually and explores themes of solitude and a feeling of being adrift. The movie uses two narratives that aren't entirely connected to create an atmosphere of quiet unease as people experience vanishings and a growing sense of detachment; however, some shifts between sections feel jarring, and the story isn’t always consistent. It goes beyond just being about ghosts, offering instead a somber commentary on feeling alone in a world dominated by technology, sticking with you through its tone more than any definitive explanations.
