I felt much the same! There were the hints that the Doctor dropped about knowing about the skin jobs (sorry, BSG moment there) and now there's the second Doctor made from the flesh, which is really interesting (having all of the Doctor's memories and all that) but I was kind of feeling like there was something I was missing too. It was like the Hungry Earth... only without the previous Doctor Who lore.

Um, not that I added much, just wanted to say "yeah, me too"
