As you also know, professor, I dislike almost everything on TV (and books and...). I am not proud of this, it is just a fact of life. However I have liked various of these series. I particularly like Heartless
Does your teenage son / daughter look like they're in their mid 20s? Are they good looking and exceptionally pouty? Then why not send them to our gothic expensive private school in the middle of nowhere without much sign of many teachers or many staff - main extra-curricular activities being weird rituals and fencing in the crypt?
Ancient curses / witches / energy vampires / plot holes / flashbacks to the medieval history of the gothic manor house that became the school / creepy aging hippies, it has them all.
As I snark above, many of the actors playing high-school students are in their 20s, quite late 20s in some cases. Obviously Denmark doesn't have the equivalent of Grange Hill to provide actors to play high-school students who are high-school age. Also possibly there is too much shagging for that to be acceptable.
Some Googling to find the actors ages finds that one is in a film presented at the Sundance festival called Copenhagen https://en.wikipedia.org/wiki/Copenhage
Another of the better series is Cenk Batu, a German police drama (apparently most German police dramas are all linked together in a meta-series) in which a tall striking cop of Turkish heritage repeatedly goes undercover in the underworld of Hamburg whilst making absolutely no attempt to disguise himself or wear different clothes and despite having a couple of undercover assignments per episode somehow his photo isn't up on the cork noticeboard in the HQ of every criminal undertaking in Hamburg. There weren't many episodes though, which makes it slightly less ludicrous http://www.channel4.com/programmes/c
For those who didn't watch it I do recommend Deutschland 83, although the ending was rather silly - as I said before they have clearly learnt a lot from British TV in terms of uneven tone and pacing and plots that don't quite make sense. And there is definitely kudos to them for thinking - well we'd like to marry an AIDS plot which would work in about 1988 with the 1983 Cold War exercises, but obviously that doesn't make sense, but never mind, LET'S DO IT ANYWAY!
