From what I've seen from the gameplay trailers, it feels like these characters have been created and written by Buzzfeed opinon bloggers for twitter people.
I didn't see enough of Baldur's Gate3 to judge characters, but that, more or less, was a problem I had with D:OS2 protagonist/companions. None of them were believably grounded in the universe and seemed to speak like snarky coop players, rather then in-universe characters. Not something I want in an RPG.
