I suppose we've been a bit spolied with both RTD and Steven Moffat both loving the show so much that their care for the character of The Doctor through the ages was reflected in their stewardship of the show.
I suppose it's possible that the current guy in charge doesn't give a sh!t about all that.
It just seems a bit like when JNT took over the show and the creative changes he made to the direction of the show. That seems to be, to my thinking at least, a little reflected in the current run of episodes.
