There is no connection between most DC cartoons. The pattern changes, the sequence of events changes, and some characters find themselves alive after being killed in an earlier film. Clark Kent reveals Lois' secret identity. There are no first, second, etc. series, there are images of events that float around the hero like a fish in an aquarium, but somehow I like it. You have to look at it all over again.
Well, this part was especially liked for its unique purity, for the hope given at the end, for the sacrifice, for the kind hearts of the characters. The hope of this world is good people. It would seem like such a simple morality, but you have to come to it with the film, and then it sounds different.
P.S. “What happens if an unstoppable force collides with an unmovable object?” – in the film, the answer to the riddle was very strange and somehow gleaned from an advertisement in the newspaper “They Will Surrender” ... to whom... why? In one voiceover translated as "They will unite." Is that a clue? You could just as easily read on the fence. It is much simpler: a force that cannot be stopped and an object that cannot be moved are about the same thing, and based on the definition of the unstoppable, the only result is that they will pass through each other without exerting any influence.
