I'm a bit fatigued from the Doc saving the world from ever more contrived/bigger/infiniter threats
I got bored of this some time ago, and it's the main reason I haven't watched since mid-Capaldi era. When I saw the trailer for the new series, I just rolled my eyes. They've saved the WHOLE UNIVERSE so many times now, there's nowhere left to go.
When I was growing up, the stories were usually on a much smaller scale - the Genesis of the Daleks was about a 'local' scrap, and even Earthshock was low-key compared to some of the recent storylines.
And the best stories of the current era are similarly narrow in their scope - Blink and The Empty Child being great examples.
