"Far from a thriller, the film forthrightly pits civilized conduct
against violent take-all survivalism: The camping vacation of a family
of four (led by scowling Ray Milland) is interrupted by a full-on
nuclear attack on distant cities; the ensuing debate about how quickly
and thoroughly to abandon law and order in order to stay alive
troubles the clan, even as Dad begins to loot, terrorize, and indulge
in vengeance killing. Gracelessly directed by Milland himself and
choked both by a finger-snapping beat-jazz score by Les Baxter and the
presence of Frankie Avalon, the movie is nevertheless an anxious,
detail-rich essay on moral collapse."
