From what I've read, mainly press bumph, Chris Chibnall's Camelot (apparently an extension of abandoned early thoughts for what became the Merlin TV series) seems to be another wrong way to do a King Arthur series, though I could easily be stupidly wrong, as usual.
I should stress that for my money the only two really good King Arthur TV shows were Andrew Davies' Sunday serial The Legend of King Arthur from 1979 and the RSC Morte D'Arthur from 1984, which was essentially a beautifully illustrated monologue with actors as moving pictures behind John Barton's finely judged reading of the end of Malory.
For me, it should be a Precinct Drama with Camelot as the big standing set- lots of writers, big ensemble cast, a new quest of the week every time, and a running back-story at court that comes together at the series end, an anthology drama series with shared secondary characters like Clocking Off.
It should be made like The Bill or Doctors with several episodes in production simultaneously, all using different leads and crews and there really shouldn't be a house style, it could be political, allegorical, gritty, funny or fantastical as each quest required.
I'd like Jimmy McGovern to show-run it as The Table, with an initial run of 8 x 60min, please. Bring it to me for Autumn 2012, ta.
