Loved all characters besides Gale. Has an interesting arc, but his dialogue sounds stupid. I was expecting a smarter wizard, but he is probably the dumbest of the characters.
All others are superb and have their own mind as you would expect. The manerisms in the cutscenes are very stereotypical and hopefully will improve to give them more personality.
I would appreciate if they made Astarion a little more evil. The jokes about blood sucking don't land well.
