As far as companion first impressions are concerned, I second this post. Larian seems to really love characters who are genuinely unlikable people only capable of communicating in blunt insults or, if you catch them in a good mood, snarky remarks.
And so what if they do?
They are based around similar characters from older games. Viconia and Edwin were my favourite characters in the original games, Viconia especially because you could actually teach her how to become good if you wanted over the course of the game.
By far my favourite character in NWN was Qara, while she had a Chaotic Neutral alignment, her personality verged more towards Neutral Evil if and when you didn't agree, trust or understand her.
On all accounts, Minsc was always my least favourite character, simply good and dumb, and Jaheira was nothing less than a whiny old hag with a temper tantrum. Aerie was a brilliantly written good character with a strong story arc, but she was very picky and needed constant nannying and appeasing to remain on good terms.
The worlds depicted in RPG fantasty games are ones that would give rise to many more evil characters thsn you get in real life - just imagine if you were actually captured by mindflayers, or constantly besieged by trolls, or approached by an actual succubus and offered to make a deal of a lifetime with the devil. You are going to be very easily tempted away from 'good' as many of the characters in these fantasy realms often are.
Games are not meant to depict real world standards of good and evil, and everytime they pander to such things as the recent removal of inherently evil races the lore and fantasy aspects suffer and diminish greatly.
