"Any time." Dad replied.
Compared with other disaster films in Hollywood, the movie Doomsday is characterized by hopelessness. In Comet Hit the Earth, human beings destroyed the comet that hit the Earth by intelligence. The day after tomorrow, the survivors of the flooded city finally moved to safety. In the center of the earth, scientists finally reversed the chaotic geocentric magnetic force ... but on the road, there was no sunshine for many years, crops and trees stopped growing, buildings rotted, and human beings were almost extinct. The rest of the "people" are no longer people-they are like animals rummaging around for the leftovers of civilization that is becoming increasingly impossible to find: a bottle of coke and a box of cans ... now they can't find this.
In a hopeless world, is "goodness" still necessary? Is it still meaningful to be a good person when life itself is no longer meaningful?
Most people in the film respond with actions: like other animals, they stare at blood-red eyes and, driven by eternal hunger, divide the world in their eyes into food and non-food, and rush to food urgently, even though it has a beating heart and speaks the same language as them.
But the protagonist and his father have different choices. They would rather starve to death than eat people. Even when they met their dying compatriots, the children insisted: Dad, give him a can.
"You must keep your inner flame", which is the agreement between father and son.
