While I am a very long time fan of the show (since 1982) I understand that it has to change and sometimes radically (Female Doctor excluded) and it has been on (and off) for 11 years in the Modern Era so when Moffat leaves there is a need for the new blood Chris Chibnall to shake things up.
Change is an integral part of the show.
But human fans sometimes are not so flexible. And the Moffat style of complexity and years long continuity somewhat works against that.
But this article I found is a good summation of this.
and this is worth watching also:
