First off took me forever to stop laughing at the term Yakuza Apocalypse LOL I mean the word Yakuza is used any time one would normally use 'Vampire' XD throughout the film it's hilarious. And really that's the basic theme, how yakuza type organizations and syndicates run on the blood of civilians. But they also show how there's a cruel system of hierarchy for even the people like evil syndicates which makes might is right the ruling directive. And anyone with lower strength is easily tread upon. This one is more like Lessons Of the Evil where it's super dark and then there will be plenty of eccentricity and dark humor but make no mistake it's bloody and gory, even more than Lessons. But not on Itchi or Visitor Q level and is watchable by the masses for the most part if you don't mind the symbolic surrealism of Takashi Miike's work which is rather heavy in Yakuza Apocalypse and always my favorite part.
