Doctor Who is a British science fiction television programme produced by the BBC. The programme depicts the adventures of a mysterious alien time-traveller known as "the Doctor" who travels in his space and time-ship, the TARDIS, which normally appears from the exterior to be a blue 1950s police box. With his companions, he explores time and space, solving problems, facing monsters and righting wrongs.

Given the nature of the show with changing actors and production teams plus the show's longevity and often low budgets it is hard to say.
I definitely think when the Doctor became all powerful to the point that he re-created the universe the character changed and became too "god-like" and less human-like.
Re-creating the universe was s step too far for me to take seriously even in the show's own universe.
