Saved watching it until my girlfriend came back from 3 weeks working abroad. Fantastic show - watched it over the last two days.
Aside from the already mentioned 80's references, I think it had a very Silent Hill kind of feel to it, and bits of it also reminded me of Under the Skin and also a film called Beyond the Black Rainbow, which is also set in 1983 and has a synth-heavy soundtrack (Jeremy Schmidt from the band Black Mountain composed the soundtrack and I half expected his name to turn up in the credits for Stranger Things).
