My sad face was not that you had posted it but more sad at the outcomes for all of them, which I already knew as I had looked Ann Lister up as soon as I got into the series. So so sad all round.
But for me knowing that won't spoil my appreciation of series 2 whenever it airs. We know know the outcomes of lots of historical people and we can still enjoy dramas about them (royalty from all ages, Winston Churchill etc)
