I feel as if the new TARDIS interior pulls back into older Who. 11th and 12th had interiors that felt homie and lived-in. You could casually pull a book off the shelf of 12th’s and there were dart boards in 11th’s.
We’ve lost the Dalek bumps 12th had and we now have interesting glowing sun pentagons and crystals. It feels more like a true ship now, I think.
