First of all, I will say, if you watched the dubbed version, then this show is a 1, if you watched it with the subtitles, which I always recommend for foreign shows, then this is a 3 or 4 Max.
Overall, don't let anyone try to convince you that you're not sophisticated or artistic enough, to grasp this show, and therefore that is the reason you don't enjoy it. It's simply not a very good show. Very boring, not intriguing enough, and quite annoying at times. The co-lead character, Sophie, couldn't be more annoying and unenjoyable, if she tried.
The show tries to be Faustian or Lynchian, but it just doesn't work. Lots of people have tried to be David Lynch, and sometimes it just doesn't work. It sometimes didn't work for lunch himself.
I love foreign shows/movies, but don't waste your time on this one
