Since these specials started, I keep feeling like RTD watched Moffat's run and was inspired. Impossible girls, cracks, more timey whimey, more oddball concepts, etc.I did like the reappearance of a crack that wasn't a crack, in particular. It is nice to feel like the people who are making the show have also been watching the show.
Not that RTD hasn't put his own unique stamp on these stories but he does seem influenced by Moffat, which is totally fine.
