It's Larian brand of writing.
Is it good? Is it bad? depends on you individually, but I am sure, 2-4 people will agree with you.
RPG and Writing usually at the opposite side of the game spectrum. If you want a good written cRPG, you lose aspect of RPG (i.e. Disco Elysium/PST), if you want total cRPG mimicking TTRPG rules and "freedom", you usually get abysmal writing (Solasta).
Or you can try to satisfy most people and risking to disappointed some, which is what Larian does, their writing is not at the level of Planescape Torment, but it sure as hell is better RPG than Planescape Torment (utilization of rules and stats against dialogue/things you do within the game).
For me personally, I think it's not "bad writing", Solasta has bad writing, Black Geyser has bad writing, BG3 is like "wide as an ocean but deep as a puddle" kind of writing, it almost like the dialogue story is only a vehicle for your RPG stats, it's on the menu but not the main course.
But then again if I want to play games with stellar writing I'd play Disco Elysium or PST anyway not cRPG.
