What’s hilarious about your comparison to the original Godzilla is that the original Godzilla has a shit ton of universe shrinkage. Dr. Serizawa, Emiko, Ogata, and Dr. Yamane, the four most important people in all of Japan, all happen to be tied together through a bunch of convoluted family drama. Emiko just happens to be the daughter of the paleontologist who figures out what Godzilla really is, she just happens to be having an affair with the salvage crewman who finds him in the South Pacific, and she just happens to be engaged to the scientist who invents the super-weapon that ultimately kills him (and is also Yamane’s protegee).
But I guess having characters have meaningful relationships with one another is only bad when Star Wars does it?
