Thanks for the heads up about this Simon. I watched the original Swedish version and thought it was one of the best things I've seen on TV ever. It was really well paced and clearly a lot of thought had gone into what the consequences would be of having human like robots around and the numerous sub-plots bore this out. I found myself thinking 'Yes, that is what would happen' on many occasions.
I watched both series in a binge before I watched the Channel 4 version 'Humans'. I thought this was a poor copy. Too rushed, trying to pull together just the best bits of the original. But in doing so they missed out on a lot of the background stories, and having seen the original I was not as engaged and ultimately I was disappointed.
It was certainly thought provoking and I can see that these are issues that society will face over the coming decades.
Highly recommended! :)
