I have now just finished watching this.
Watched the first two episodes with my 13 nad 16 year old before I realised that the educational aspect was not going to make up for the horror / trauma of it all so have said: 'sorry, no more' to them and finished it off myself.
I think the horror / Tunbaac aspect of it was overdone and took away from a story that had enough 'natural' horror in it anyway.
The men would have hallucinated from lead poisoning and then starvation, quite apart from the mental rigours of depression and anxiety about being stuck in a wilderness with little chance of escape.
It beggars belief that the British didn't accept help from the indigenous people they met. But I guess it was set around 1840/50 and times were different but that part of it is hugely depressing.
I'd be interested to know how much of it is factual re the characters and how much of it is supposition? Hickey for example? Goodsir?
There was an exhibition down in Greenwich, I think, which includes some of the items recovered when the ships were found which I was thinking of taking the kids to but I don't know if it's still on?
