New Companion: Spunky; clearly capable of independent action. Definitely promising, and I'm looking forward to seeing how they grow her character. But I'm not yet thrilled. (To be fair, I actively disliked Rose for her first few episodes, but now she's my favorite companion.)
New Executive Producer & Head Writer. Oh, yeah! I was never an RTD-hater, and I think he wrote some fine episodes. But Moffat's episodes have always been the strongest, and I look forward to seeing where his vision takes the Doctor.
