You're making a number of unwarranted assumptions here, my friend, but for reasons of confidentially and professionalism I can't tell you which ones or why they're wrong. ATimson's reply above only scratches the surface. I'm sorry to pull this card.
As for whether or not Bill was "the one dimensional person," I don't really see that. I saw a character with a lot of "edges." True, the edges weren't always developed -- or developed well -- but they were there, right from "The Pilot." She was, imho, a better developed character after one season than Clara was after her first season.
