After a battery-farm chicken escapes death’s clutches, it finds sanctuary in a seafood taverna on the Greek coast, only to cross paths with a gang of unruly thugs. What with EO, Cow, and Kedi, cinema seems more interested in the inner lives of animals than ever before. György Pálfi’s nail-biting drama Hen is the latest in this creaturely canon, offering a bird’s-eye-view of human affairs.
