That's an extremely unusual and very broad definition of wacky if I may say so. Korgan I would say is well characterised and stays true to that character throughout. The Planar Sphere is an interesting and well implemented locale, the Underdark much the same. I would add that in comparison I find Pillars companions about equal all told, Durance and Korgan two of my favourite characters would no doubt get on like a house that they'd set on fire. Whereas if you are saying that Poe's locales suffer in comparison to BGs, then I would agree with you. The easiest example is Durlag's Tower versus Od Nua, nothing need be said here.
As for emotionally touching, I really wasn't affected by the BGs in this manner, Torment yes, the Ultimas of course, Krondor without a doubt, but the BG series was just an ARPG to me. Though as i've said before this is coloured by playing through the Ultima saga before BG and seeing it as an enormous decline in terms of features, worldbuilding, non combat gameplay, exploration and thematic strength.
Edit: I never went with a six man party in IWD, always used four, far better in my opinion.
