Never heard anything about it ==> read @dun
pealhunter's comment(s) ==> looked for trailer on YT ==> thought "OK, interesting" (even it is british) ==> watched the first episode.
Result: SICK, SICK show!
It's like a modern/high-tech version of "Outer Limits" from the 90's wich I loved so much because of his outstanding courage NOT having a happy ending, but moral lessons.
So far every episode of season 1 has been a nightmare :)
for the hint!
