TV-series suggestions?

I am looking for a series in the thriller/horror-genre. I love American Horror Story, especially the first season. I recently watched Les Revenants, which I absolutely loved! Other than that I can't think of much else…

Just to be clear, I am not looking for The Walking Dead, Falling Skies and those types of series (I am currently watching them too, though). I really want the creepiness-feeling that AHS and Les Revenants do so well. American, British, French, German, Danish, Israeli… whatever, as long as it exists with English/Scandinavian subtitles I'm happy :) Thanks!
