This has been a wonderful series, its great to have a story stretched over 2-4 episodes rather than 12-30 which seems to be the norm now. Of course this was a 3-parter so it was perfect.
I am not at all familiar with this story, as I imagine most others aren't either, but it was a thrilling little adventure, though I have to admit certain plot twists weren't entirely surprising it was still gripping and fast moving.
JR was fabulous and very believable in her role, the energy and feistiness she brought was great. And I just adored her outfits too. I look forward to seeing more of her in this role, and others. She thrives in the 1950s it seems.
David Walliams, in my opinion, was entirely miscast. I could count the number of times his facial expression changed on one hand. He just appeared stunned/frozen all the way through, even in the parts where you would expect a deeply strong emotional reaction to someone you love being in danger or a facial-flutter when your own life threatened or you are caught out by someone.
He just came across as unenthused, lacking energy and uncaring like he couldn't be bothered to act. If that is how the character is MEANT to be then that's a different matter, but I think he was going OTT on the old fashioned 'stiff upper lip' quiet, introvert and calm etc etc.
And frankly I didn't think the chemistry between them was zinging.
This aside I will watch the next story and hopefully this will improve. Overall it is a wonderful show, just let down by the lead male.
