I enjoyed the first episode of Humans and will definitely keep going with that.
The only problem it really has at this point is me. I have seen too much TV/Movies/books which go heavy on these same sci-fi themes, implications of artificial intelligence yada yada.
Nothing wrong with that as a subject. And it's not that this show is unusually heavy-handed.
It is just that there is only so much to say about it in terms of philosophical angles. I've heard it all. But they have to walk through it and lay down the foundation.
But other than a couple really obvious peripheral characters, it is interesting enough so far.
