Yes, it has bothered me somewhat, ever since I read the following.....
Moffat said of his decision to quit: “Feels odd to be talking about leaving when I’m just starting work on the scripts for season 10, but the fact is my timey-wimey is running out. While Chris is doing his last run of Broadchurch, I’ll be finishing up on the best job in the universe and keeping the TARDIS warm for him. It took a lot of gin and tonic to talk him into this, but I am beyond delighted that one of the true stars of British Television drama will be taking the Time Lord even further into the future. At the start of season 11, Chris Chibnall will become the new showrunner of Doctor Who. And I will be thrown in a skip.”
So Chibnall was hardly chomping at the bit to take over.
Not, to my mind, the behaviour of someone who is going to do a turnaround and suddenly have an enthusiastic or passionate vision for the show. Well, not one that lasts for very long anyway.
We shall see how things develop, I guess.
