Snowpiercer for kids, as someone put it. I think it muddles its political points too much to warrant such comparisons, but it’s apt.
The subtext of having a motorised ginormous London gobbling up a simple Bavarian town of lederhosen and thatched roofs overwhelms the senses. There are speeches about how they shouldn’t have come to Europe while the common folk cheer the financial capital of the world steamrolling over everything.
London is summited by mostly intact St Paul’s Cathedral who turns out to be a Manhattan project to nuke the wall between the East and the West. The quantum nukes are even fired twice, but this time the nuked party is not defeated. As to prove they are superior, the London refugees are received with literal open arms.
The Chinese money can almost be smelled. Not as much as, though.
