Set largely in a Melbourne that’s settled into a kind of resigned funk, the somber film makes catastrophic destruction feel real by portraying its effects on a handful of people, including a U.S. The film’s characters say a long good-bye not just to their own lives but to humanity itself, and the focus on a few characters living in a country far away from the action makes it all the more effective. Their fate, and Australia’s, has been sealed not by their own choices but by those made by faraway strangers. Though Kramer can’t resist some moralizing in a heavy-handed (if effective) final scene, it plays less as a cautionary tale than an attempt to come to terms with what at times seems an inevitable apocalypse. But at no point does the film sell short the horrors of the radiation poisoning that’s slowly, but inexorably, making its way to Australia’s shores, describing what follows the early symptoms as a fate worse than death.
