21st-century Who's peak was the Matt Smith seasons.
Go back and watch his Christmas specials, particularly A Christmas Carol. Watching it now, it's like an alternative universe--the episode is endearing, filled with traditional nods (obviously Dickens, but even on a moral level, not just a surface one), it has a beautiful girl and a normal healthy romance story in the middle, the alien planet even sings thoroughly Christian carols at the peak and no one seems to be wringing their hands in nervousness about it. The whole thing is openly made to appeal to the best and most universal sentiments of the average viewers, without even a hint of trying to offend or include hot political & social elements.
