I find programmes such as WDYTYA easy viewing and there have been some very interesting family histories surfaced. I am thinking of Boris Johnson, Barbara Windsor, Jerry Springer, Carol Vorderman, Jeremy Clarkson and many more.
I think the history of the Whitehalls was another interesting programme not only for their family ties but in relation to the history of the politics of ' that era'. None of us can be held responsible for what our forebears did but they took it on the chin.
The fact is some who have watched the father son double act over time understand how they function, how they take the Micheal out of each other, usually Jack over his dad who is the dead pan character usually with strong views of which his son often does not share. They obviously have a strong bond humour wise and family wise.
If you know nothing of them you will judge by what you see and that can distort what was happening by them using their usual natural form of banter/dry humour to counterbalance the feeling of embarrassment about what the programme raised in relation to their forebears. It was patently clear to me for example Jack Whitehall was not ignorant of matters about the Transportation to a Penal Colony as somebody mentioned, it was his style of dry humour to ease the situation of what he had just heard about hang, drawn and quartered and what had happened. You either get that or you don't, as always each to his/her own.
I take my hat off to those who engage in the programme, for better or for worse!
