How to treat the setting of "traction city" in the future world in "City of plunder"?

Thanks to The Lord of the Rings's team and the writer and producer of Peter Jackson, the whole new world created by The City of Plunder really caught people's eyes for the first time. Whether it's a mobile giant city like "Hal's Mobile Castle" or a cloud station like "City of the Sky", these truly magnificent grand scenes make the film live up to expectations in production. However, if you take the city of plunder and The Lord of the Rings for example,

With the development of the plot, the setting of this mobile city, which brought a lot of visual impact from the beginning, failed to make people see its real charm. The city of plunder has a grand pen, but it is very lacking in details. This is not only the construction of a mobile city, but also the transmission of water. Even the movie didn't explain too much why such a mobile city should be built. The lack of details makes the film just a castle in the air.

As an adaptation of a novel of the same name, although I haven't seen the original, I can still see from the film that the original should be a concise steampunk novel, and a serious problem in The City of Plunder is that I don't know what to choose. For two hours, the film aims to build a grand steampunk world, and at the same time, many branches are interspersed outside the hero and heroine. Obviously, for Christian Rivers, who directed the film for the first time, he didn't shoot for it.

The confusion of the plot directly leads to the problem that the behavioral motives of all the characters become unconvincing, and the film can no longer organize the emotions of the characters and build a profound core for them. Although there is a discussion about urban Darwinism in "City of Plunder", love and hate are intertwined, but the facial characters and unremarkable routines make these internal expressions appear immature and promiscuous in the film, which simply makes people unable to identify with their feelings.
