Director David Yates suggests the transition in subtle ways, one of them by making Hogwarts itself seem darker, emptier and more ominous than ever before. Its cheery corridors are now replaced by gloomy Gothic passages, and late in the film an unspeakable fate befalls the beloved Dining Hall at the hands of Bellatrix Lestrange (Helena Bonham Carter), who seems to function principally as a destructive vixen, but no doubt has more ominous goals.
