On the topic of Doctor Who and Capaldi, I recently went back and watched his episodes in both the third season of DW and in Torchwood’s third mini-season (Children of Earth). If those are an indication of what’s to come, we’re in for a treat IMO (though I do wonder if they’ll ever reference his past appearances - especially if they ever plan on bringing back Capt. Jack, in light of his interaction with Capaldi’s character in TW).
