I agree with the comments about padding and war history.
I also think (and have done for some time) that the BBC are again trying to appeal to all and sundry by choosing their subjects for this programme not necessarlily for their interesting ancestry but more because of their current popularity.
Thus we have from the very popular Bake Off Paul Hollywood for this series and Mary Berry from the last series. We also have the two leads from Last Tango In Halifax (very popular): Derek Jacobi and Anne Reid.
We'll probably get the actors who play Mr & Mrs Poldark in the next series!!
Interestingly, I watched a few of the latest series of WDYTYA USA on the Watch channel a few weeks ago and - I hate to admit it - they're now doing it a heck of a lot better than us! They had the story zinging along; lots of experts and documentation, and, above all, by and large they didn't stop at one ancestor but kept going back. Kelsey Grammer's story was brilliant, as was Jim Parsons.
I hope our series improves as we go on....
