In all honesty, I've been holding off on reviewing the game because it is in early access.

I would give metrics such as

Music: A (not an A+ only because there is not enough of it. Sometimes the Underdark is really quiet and I can't tell if it's a bug.)
Visuals: B+ (For early access everything looks great or is heading that way.)
Voice Acting: A (The quality and quantity of it is blowing my mind.)
Narrative: B+ (I'm worried we may lose plausibility down the road, as long as the story stays plausible it's an A.)
Combat: D+ (Larian has put a high bar with their prior games, combat is currently too repetitive because of generic mechanics being overpowered, etc.)

Most passerby are saying they're doing great for early access. And my early access review wouldn't change that.
