The models are high quality but the rigging/capture for the facial animation is pretty awful.  Everyone looks like they have facial paralysis or something when they talk, particularly if it's a minor cutscene.

My guess is that they hand animated it instead of using actors and mocap, it's been a while since a AAA game had cutscenes that were animated this poorly.

No they probably did what Mass Effect Andromeda did and used an ai animator to create facial animations.
