It depends how intimate you are with IWD and BG. Like, if you've played them or not. I haven't seen anyone who has played both say that IWD backdrops don't look better than BG ones. And I haven't seen anyone argue that BG2 has better paperdolls and mundane sprites than BG.As for the constant comparison in-between IE games: it is a complete waste of time. I wouldn't be able to tell if IWD was better looking than BG, and even if I would, it'd be my subjective opinion anyway. But it is clear that the two games differed in theme and graphics too, and imho the theme was in sync with the art style in both games, and this is all what objectively matters.
Maybe people just don't like the white ice&snow visuals of the first Icewind Dale areas, and thats the memory they have left of it when they fail to exist that forest whatever-it-was-called.
