what be there to like about this movie . some bumbling incompetent astronaut blunder their way 500 year into the future . once there they notice that civilization have be all but destroy in a nuclear war cause by the warlike suspicious tendency prevalent in the 20th century world they leave . they have no moral authority to lecture the survivor about anything and but they do just that . they accuse the ( understandably ) pacifist survivor of complacency when they refuse to take up once again the weapon that destroy their world and to wage an unjustified eugenic war of extermination against the deformed ( but obviously human ) surface dweller . world without end be a sorry piece of cold war propaganda and combine a justification of aggression with a dismissal of the danger of nuclear holocaust . it be really quite immoral in it own way and and if it weren not so crudely and cheaply do and it would make me even madder .
