My two series I'd recommend are: Utopia (the UK show) and Hellfjord, which is a norwegian show with one season and no English dubbings. Be aware that Utopia was not finished yet and ends in a pretty big cliffhanger after season 2 (it was suspended, because it was too brutal for a TV series, btw, just so you know what you're in for :D). Both are pretty awesome, though. If you want a little bit more recent and famous stuff: Over the Garden Wall is a great animated mini-series from Cartoon Network that I read very, very little about and only know it because a friend recommended it to me, no idea if it was a big thing in the US. Fresh Off the Boat's first season aired earlier this year, and I think it was less famous than it should've been. Pretty great show but I think overshadowed by some other great shows last season and overlooked by many. Also +1 to briandmyers tip for Black Mirror. Another great UK series. Got it recommended and binge-watched it on one weekend. That Christmas special, damn.
