Syndromes and a Century is the latest film by highly regarded Thai director Apichatpong Weerasethakul, currently the subject of an NFT retrospective. It's an elegant, puzzling, humorous movie, the first half set in a clean, well-lit, rural hospital, the second in a bland city hospital. It's underpinned with thoughts about Zen Buddhism and reincarnation. As Ken Tynan said of Waiting for Godot, nothing happens, twice.
