I do think the BBC are desperate because under the current Showrunner, the ratings have fallen off a cliff and the writing has been god awful on top of poor preformances by the actors, I gave Jode's era a shot and frankly, I was bored by the Kablamman ep and stopped watching, then I heard the promise of changes for the next season, so I tried with Spyfall and found NOTHING had actually changed, they only bought in the Master who was just plain lame and didn't really seem to have a plan, Missy was a much better character and had a much better actor playing the character, sure the Moffet era had its ups and downs but at least he was trying to entertain people, the current era, feels like it was written for those who put something on in the background and not really care, sort of, day time TV or boring soap operas that are on just before the start of what was "prime time" TV! With Davis return, hopefully there will be some quailty writing once more along with visuals and music but with the BBC and Hollywood going all in on this divserty and inclusion BS, I worry that he will be strong armed into doing just that, despite his previous sucess, so the BBC faces a uphill battle if they want to get the show back to its previous heights, if he can't turn their fortunes around for the show, they might as well put it on hidus once more, its not like it has been "MUST SEE" TV any more!
