OK, caught up now but you've probably all gone away 
I love A Place to Call Home. I think I discovered it when the BBC showed the very first series, and I was off work sick and watching daytime TV. I've watched every series since.
I'm struck by how much Sarah's character has changed. She was a wonderful, feisty, attractive woman in the first couple of series, but I agree with FUzzyCustard above that she mostly floated around whispering moody nonsense this time round. Apart from where she nearly killed the ex-Nazi, which was the Sarah I used to know and love!
I couldn't work out right till the last episode whether Evil Reggie had turned over a new leaf or not. Most of the series I thought she was attempting to play some kind of double agent game with Sir Bad Man (with moustache) and was in over her head. But I didn't believe she was really trying to make amends.
I think the only way they could make series 6 after tying up so many loose ends would be if the conclusion about Reggie's death is wrong after all, and Sir Bad Man (with moustache) is still out to get them.
Not really related, but I'm reading Trust Me by Lesley Pearce at the moment, about the lives of two women who are sent out to Australia as 'orphans' (only they're not, their father goes to prison for something he didn't do) and are put in those awful orphanages and then sent out to work basically as slave labour. I keep finding myself thinking that this would have been happening in the same country as A Place to Call Home, at the same time, and who knows, perhaps not that far from Inverness.
A last thought. Do Jewish people keep menorahs burning in the windows? That was what Elizabeth said she would do, but I've lived in Jewish districts and never seen this.
