Let me put it like this. If Larian remade BG1 and 2 and their DLCs, and they stayed true to the original game, I'd love it. But again, to pull that off would be next to impossible.
Imagine scenes where there is no voice acting in the original, so there's just subtitles. Now picture the characters with cinematic closeups, mouthing the dialogue but no voices because no voice acting for that part.
Again, unless they rounded up ALL of the original cast and got them to voice act all the non-vocal game dialogue, it just wouldn't work.
They'd probably need to hire new voiceactors because of this.
