The universe started revolving too much around The Doctor around the start of the SteMo era, & it was a gradual downward trajectory from there. Chibnall or RTD2.0 could have course-corrected, but both made it worse instead. IMO what was so cool about Classic Who was that he was kinda Just Some Guy™️
I don't want to point any fingers but I do actually and a big chunk of this is your fault mate. Jesus Christ.
