Have you by chance read Tolkien’s version of Sir Gawain and the Green Night?
I suspect that the new Downton Abbey movie will be a good non-biopic traditional drama; that very type of movie you mentioned.
It will be eagerly anticipated, given the popularity and acclaim that the TV series had.
I hope that it will also be well-received!
Over the last decade or so, there have only been two episodic TV series that I’ve watched with any regularity: Downton Abbey and Game of Thrones.
