This is sort of how I felt after the Eleventh Doctor's departure: I was really, really worried that the nature of the show would change, that it would stop being about hope and possibility and love. (I got fairly burned by RTD Who and the attempt to make the Doctor into Yet Another Tragic Hero, so.) I found Twelve really hard going, for that reason - his time with Clara just felt so grim to me, even though I could intellectually appreciate what Moffat was doing with Twelve and Clara. But (I'm only halfway through series 10) I've really been liking him with Bill - and completely loving her.

So I am swinging back toward optimism with this show, which is a really nice feeling, considering how much I loved it!
