Unless a comet can be destroyed before colliding with Earth, only those allowed into shelters will survive.
Mediocre and quite tedious doomsday movie that makes one long for the apocalypse - and disappoints in that aspect, too.
Halliwell*: "Something of a feel-bad disaster movie, in which the world is almost destroyed, while the audience is slowly drowned in the sticky syrup of sentimentality. What is truly striking is the poverty of imagination: the end of all life is a theme worth more than the trivial psychodramas on display."
Maltin***: "Exciting yarn...Freeman is the rock-solid U.S. president, Duvall a veteran astronaut on a space mission to explode the comet; their authorative presence adds weight to this saga, while Leoni seems a bit of a flyweight as the ambitious TV newswoman who breaks the story."
