Well if there is a thin line then you should be extra careful not to cross it. I mean this 2020 and there are tons of great examples to look after. Witcher 3 is a 5 years old game and has 1000 times better facial expressions than BG3.
That's a general issue with the game, though... the "cinematic" approach was a bad idea to begin with, to be honest. It's almost like Larian isn't trying to make a Baldur's Gate follow up, but a Dragon Age 4 or - better - DA Origins 2, while, sadly neither having the directing nor the writing skills necessary to really make it work.
