Gives Ten an equally important role to Eleven in his anniversary special, Makes RTD's Time War central to the episode's storyline, and resolves it in a way that doesn't undermine Nine and Ten's character arcs, gives Billie Piper a major role without infringing on Rose's storyline, gives Paul McGann the regeneration story he deserves, gets Tom Baker back on the show one last time, and gives us one very brief, tantalising tease of the next Doctor. And all this was while having no actors under contract, and BBC executives constantly interfering.

Chris Chibnall

Used his final story to bring back two beloved companions from the classic era, and gives them closure with their respective Doctors. Brings back several Classic Doctors and the Fugitive Doctor to aid Thirteen in her final battle, and revealed that companions from throughout the Doctor's life have been getting together and supporting each other, as they will now do for Yaz. And this was in the aftermath of the pandemic, and at a point when a new showrunner couldn't be found, with no idea what future the show had.

Russell T Davies

After getting near complete creative control of the show in time for the 60th anniversary, burns the Thirteenth Doctor's outfit away, immediately pivots back to his Doctor and his companion, with just some old villains to represent the other 55 years of the show. Doesn't bring back any other elements from the show's history until the third episode, and even then, has Mel and Kate play second fiddle to his characters. Doubles down on the self-indulgence of The End of Time by refusing to have Tennant regenerate at all, uses the Fifteenth Doctor's introduction to give Ten a happy ending rather than letting Ncuti Gatwa define his character on his own terms as every one of his predecessors has done. And writes the Nobles (his characters once again) as the one true found family the Doctor needs, as though the Ponds and River and Clara and the Fam were just passing acquaintances.
