The cinematics are for the most part terrible; a mute expressionless doll for the main protagonist who perpetually has his/her hands on their hips and sometimes raise their eyebrows? Please, the game is littered with badly directed and totally unnecessary cutscenes. It's a budget sinkhole.
It is 1000% better than DOS2. Words can't express how happy I am with having actual visual storytelling in BG3.
There's really no comparison. BG3 isn't perfect, but it does a decent job. Check out the DOS2 scene on the beach starting at 1:30. Compare that with the Astarion scene.
