There’s a series on PBS now called “World on Fire” which came across to me almost as a Brit-centric version of “War and Remembrance”.
But I was put off by the gay sub-plot, although I did like the scenes that were based in Poland.
(And the young actress in it, was in the great Polish movie “Warsaw 44” which is on Amazon Prime Video)
I started to watch and checked the reviews and most were bad so I opted out and did not watch it.
