The trouble is a lot of it seems contradictory. Moffat resents the fact that RTD had more sway then him, yet apparently he's so all powerful the BBC can't shift him?
And Eccleston procrastinated so much and pulled out at the last minute that they had to get John Hurt in? Does anyone seriously imagine you just call up John Hurt on the spur of the moment and offer him a job?
If any of this is true though I, as always, blame the BBC, though somehow I doubt they'd risk Who careening down a mountain just to keep three episodes of Sherlock a year. Moffat might take his bat and ball and go home but only with Sherlock, Who isn't his.
