I agree, the two killers are amazing.
This show seems like a movie not something that would be put on tv.
I hope it continues, it certainly was creepy. Kinda reminds me of The Black Mirror, another show I hope makes it back for a second round.
Way to go Britain, finally in the last two years they have had some real good shows come out.
Does anyone know if there is a theory discussion anywhere on the web for this show? I would love to see what people are saying and add my own ideas.
