I agree with grapefruitpip, though I did watch it all. It’s nowhere near the standard of the earlier series. Partly the script, which is far too obviously aimed at the American market, but mostly because Olivia Coleman is just not convincing as the Queen. She looks all wrong, moves all wrong and hasn’t got the hang of being both regal and human.
Harold Wilson, on the other hand, was excellent (and I did meet him). I also thought the teenage Princess Anne was very good. This was probably in a later episode - I’ve watched about three.
