Frankly American superhero comics also have(/had) notoriously ex positive dialogue. I feel like it has its DNA in classic pulp books, which, like comics and shonen, are long form stories in a short form format, which can't rely on their readers having read the previous issue(s) (or sometimes just want to refresh memories because it's been a while). TV these days has recaps, I recently read the third book in a fantasy trilogy that tried a recap, but '"Ok, but what are we going to do about the dark lord?' The dark lord, Jathaniel, had turned out to be the actual murderer of Pomme, Gam's dad, who we had all thought committed suicide. He was seeking the crystals of wonder..." is still very common in modern books. Comics and cartoons are expected to have much less narration, so they tend to put refreshers like this in dialogue. Movies do that to make themselves feel like comics or cartoons. I'm not sure why non comic or cartoon movies do that.
