Demon Slayer is an entertaining work, in a sense, as a 'social phenomenon'
It’s honestly a mix of “it's genuinely entertaining, but not the kind that changes your worldview.” The setting and world-building are well done, like an evolved version of classic shonen manga, but the social-phenomenon-level buzz seems less about the storytelling genius and more about how all of this—easy-to-understand emotion, clear character appeal, media strategy, and an atmosphere that everyone can share—came together to create it.
