I'm terribly sorry that you feel that way. That sounds like a really scathing review, and mostly sounds like you're not enjoying the game at all. Would a "good" aligned companion change your mind? Possibly not, as you seem so upset about it all?
I can't make myself agree with any point you've made, though, as I personally enjoy all of the conversations, characters, voice acting etc.
I doubt there will be a complete re-write of the game/characters at this point to start from scratch.
Please take no offence, but you've missed my point completely.
I don't want any characters rewritten, I want options to deal with them as they are.
