Yeah, that was goofy, as if the aliens could care whether we blow ourselves up or not any more than we would be inclined to stop a colony of balck ants from attacking a colony of red ants.
Exactly.
During the 1950s Hollyweird screenwriters were subliminally pushing the Communist agenda.
Now they do it openly.
Yeah, it's not like human beings ever feel annoyed by ants or would do anything to harm them!/sarcasm
The point of the original movie (but not the original story) was that Earth was apparently poised to begin venturing into space and militarizing it. The aliens didn't care a whit whether we Earthlings "blew each other up" or not.
As Klaatu explicitly stated at the conclusion of the film, his people had created a police force of intelligent, completely autonomous super-robots to whom they had entrusted total discretion in dealing with any gesture of interplaneetary aggression on the part of one species against another.
Klaatu had come to Earth to warn us that his people were powerless to stop the robots from annihilating humanity if we were ever to act aggressively in outer space.
Of course, the movie is guilty of one laughably optimistic presupposition, namely that, in the 1950s, Earth was on the verge of being capable of performing acts of interplanetary mischief which might have attracted the attention of robotic patrols cruising around the Solar System in their flying saucers or warranted their intervention.
But on the whole, the film displays a high degree of internal logical consistency extremely and has aged remarkably well.
I see absolutely no need to remake or "re-imagine" it.
By the way, in case anyone is interested:
"Gort, Klaatu borada nikto!"
means
"Gort, revive Klaatu!"
