In other words, adult.Souless, lacking a single drop of whimsy and childlike joy.
Older Jap movies like 7 Samurai, Ran, Rashomon and many others are wonderfully adult, thoughtful, serious. Same for books, with authors like Murakami or Ishiguro. Even older anime stuff like Ghost in the Shell or GitS: Innocence are very serious, mature movies. The Japs used to be very serious, masculine, properly stoic race.The Japanese are not a philosophical race.
It's only in the last 20 years everything Japanese degraded into the most juvenile, infantile retardery and modern Jap authors who grew up in this culture are no longer able to even conceive anything deeper or more serious than Pokemon. And with nuAnime popularity skyrocketing in the West I'm guessing that's what awaits us too. In a decade or so playing as 5 year olds with squeaky voices are all we're gonna get in our RPGs.
