I sobbed at the arrival with Roger of the severed children. I don't remember them in the book looking shaven-headed and grey-faced (as if released from a concentration camp in 1945) but I think - to inject a slightly positive note - they showed that the others were feeling discomfort and disgust that they knew they needed to get over (and did).
The young nurse also, who'd been severed - she was very good.
But yeah, they haven't really scratched the surface of what PP wrote into the relationship between human and daemon. It's such a waste of all the good bits - for example, Ruth Wilson is fabulous, Trollesund looked perfect, Iorek likewise, Scoresby is great and ambiguous, I love how they've realised the Gyptians and I love how some of the main characters aren't white, that feels good and right. But you know, to realise some of these things they have spent a lot of money, but saved it on the daemons?
I still maintain that the writers of the adaptation didn't 'feel' the human-daemon bond and saw the books as a story first and a different way of being second.
