After our allotted decades on earth, during which we pass the time by eating, drinking, smoking, having sex, working, watching TV, going on vacations, becoming sports fans and taking up hobbies, we are suddenly catapulted into a realm where we will spend eternity in either infinite bliss, or infinite misery. If we lived in full belief and full consciousness of such an eternity, surely life would drive us mad. The risk of damnation would be too great to allow a moment's relaxation, and indeed some of the saints seem to have been deranged by such fears, their insanity passing for holiness. He is not trying to proselytize or convert his viewers, and indeed I imagine some believers will be quite offended by this film. What he is doing, from a secular point of view, is examining the logic of the final judgment as radically and uncompromisingly as he can.
Movies are often so timid.
They try so little, and are content with small achievements.
