Now maybe you think turning The Doctor into Jigsaw from the Saw movies makes the show more adult

I don't, but it does sound like a cool idea for a fan film.

I have to deal with lots of hard gray decisions and situations at work and in life. I come to science fiction for entertainment and neither want nor expect complex/deep plots with a "figure it out for yourself" moral structure.

My favorite Star Wars film is Return of the Jedi, so no, I clearly don't want to make Doctor Who or any science fiction more "adult" than it already is.
