Yeah.. thanks to the Americanised crap that was 'Miracle Day', I believe they're trying to write Torchwood out of canon.... or at least ignore it as much as possible.
Personally, I'm still not sure what to make of this. Having had some time to think it over now, I'm still rather worried about the choice. While I loved the 'silliness' of recent series, I do admit that it was getting a bit OTT. Doctor Who is meant to be scarey, and the over abundance of comedy has been loosing that of late.
Now... For those of Doctor Who lore... could this be something of the 'Valeyard' Doctor? The Valeyard was meant to be an incarnation of the Doctors darker side between his 12th and final incarnations.... with Capaldi being the 12th Doctor, and John Hurts dark version appearing... maybe they are going the darker route with the character?
Anyway.. I'm willing to give him a chance, but his previous acting isn't giving me any hope.
