I'm a (very) latecomer to period dramas. "Downton" had long since finished before I began to tackle the 50+ episodes and what a treat that turned out to be. It would be asking a lot for any series to be its equal or even come close but one that really impressed was "The Gilded Age".
I have not seen the original "Belgravia" for the simple reason that I had never heard of it but will find it to watch.
This latest "Next Chapter" seems to be taking a lot of flak from what appear to be seasoned period drama viewers so who am I to argue?........but I will. I thoroughly enjoyed it and the final two episodes were extremely moving.
I found all of the characters to be interesting in their own way and, of course, anything with a music score by John Lunn is always worth watching.
