Hm, a lot of different opinions here! My biggest impressions:
Karlach: Didn't enjoy her. Felt a bit like a character out of a children's cartoon personality wise to me.
Halsin: Loved. His personality was more layered than it seemed at the surface. Always a sucker for 'personal sacrifice for the good of the people' types.
Gale: Something about him made me uncomfortable. Can't really put my finger on it. He has some sweet moments, but I had difficulty keeping him in party because he somehow made my skin crawl.
Wyll: Total prince charming. Was very sad he lost so much content from EA. A good mixture of sweet and strong. And his VA was amazing.
Astarion: Thought his hair was a bit silly (it was a strong first impression lol), but his dorky, morbid sense of humor made him fun to keep around constantly. A party staple.
Minsc and Jaheira: I got the sense they were both very powerful, despite surface appearance. Still waters run deep here.
SH: she was really unpleasant and unenjoyable to talk to. I didn't feel inclined to "impress her" in order to get her to open up. Also her bangs felt so silly. Stuck through it, and by the end of the game I really liked her!
Lae'zel. Ride or die from first meeting. I loved how straightforward and harsh she was, and seeing her convictions get challenged later on...her writers did a great job with it! A well rounded and well thought out character imo.
