I watched North and South only recently, on catch-up, and thought it was excellent. Also liked The Buccaneers; I was surprised as I find Bridgerton just too light and fluffy even for me, but The Buccaneers seems to have a bit of heft to it.
Recommend: sorry if this has already been mentioned, but I can't remember the name, but it was set in a fancy London hotel in WW2, sort of upstairs downstairs vibe with storylines for both staff and guests. Only had one season, which was a pity, I hought. Named after the hotel, I think. Steven Macintosh might have been in it.
