I do think that's true. I also think it's becoming too difficult for them to continue with the showrunner model they have. It's too much to expect that a single person will have mastered both the production side and the write a large portion of the scripts for a complex show like DW. That's no fault of anyone, just that it's almost impossible to do! Those are two very different and very specialized skills. Get two different people to do them!I'm beginning to think RTD was the exception rather than the rule.
