It fell apart in the Capaldi era. The "kill the moon" was the "jump the shark" of neu-Who
But yes, the moon suddenly reappearing in between shots, perfectly fine and identical to before, was very silly
Capaldi was a great actor and it was nice that he got some good scripts (I really liked the one where he was in Doctor Prison, great concept), but his run felt to me like a show running out of ideas.
I didn't watch the Whittaker doctor. Heard it was awful and wasn't surprised. I eventually saw the pilot and it was indeed, awful.
Also implying that the wheels weren't kinda getting loose when 10ant said his final farewell at that (otherwise fairly underrated IMO) episode where the Master was hungry.
