Julian Fellowes ( a conservative peer) creator of DA has a new series out in the UK called " Dr Thorne", an adaptation of an Anthony Trollope novel. It's getting good reviews in the UK. Not sure if any Channel is picking it up here in the US.
I subscribed to the cable tier for BBC America. I was sorely disappointed in the all StarTrek:TNG all the time. It did occasionally have a short-run drama series. I dropped the tier a couple of months ago.
PBS has more British programs than BBCA did. I also watch many British drama series via Netflix and Amazon Prime. There is a streaming services that offers many of the British TV series for about $6 per month. It does not have some of the BBC programs, such as Doctor Who.
I heard about DA on FR about the time Season 2 was to start on PBS. I binged on Netflix to catch up. I liked it from the first episode.
