Given the lack of improvement in many areas, I am getting a feeling that the cutscenes will not get much more polished than the current state. I think we are reaching a plateau already.

My major problem is lack of artistic direction which makes them look very artificial compared to many AAA nowadays.

The voice acting is superb though.

Regarding the originals, BG2 was indeed dark to its time and the writing and acting were very solid as well. Nowadays, post-game of thrones era (just a mainstream example), definition of "dark writing" has changed considerably and apart from a few parts in BG3, the writing is mostly silly.
