"The White Queen" (BBC1) looks pretty good, if very dark with only candlelight. But at least I don't keep shouting, "Switch the light on!" at the TV as I do with Scandinavian murder mysteries. Unlike the lighting, though, the language is very modern. We have "Who eltse?" with that epenthesis (extra 't'); we have things like: "That 's the safest option". We even have upspeak!
But best of all we had Lady Margaret Beaufort praying and speaking directly to God: "Give me a sign. I need a sign right now!" Beyond Downton: spiffing stuff!
