It sort of makes sense to me within the domain of literary fiction. Mordernism was all about showing the cracks of the modern world - disintegration of institutions like religion, the damage done by WW1, differing-perspectives/unreliable-narrators, proliferation of media, abandoning rural life, etc. Modernist literature strained to show/express these cracks. Post-Modernist literature simply accepts them and works from there. But yeah 'what is Post-Modernism?' is one of those 'ahhh, ummm...' questions.
