The plot / writing feels like it was put together by a 13 year old, or maybe an AI. it's almost interesting, and almost makes sense, but doesn't. Things just sort of "happen", and they don't really make sense and aren't really explained. Character motivations are unclear. Also, the gameplay is shit.
The world they created is super compelling, which seems to always be the case with Final Fantasy games. I just wish they could make an actually good game to go with their top tier world building and art direction.
I don't know if a series can have good writing after it's been running so long that the writers they're hiring got started by writing fanfics of it.
I haven't played a Final Fantasy since number 6 though.
