I loved Dark, I think it's one of the best things I've ever seen so I was highly anticipating this one. 4 episodes in by now and must say I prefer Dark.
The story isn't bad by any means, the location and videography look cool and I've some suspicion that the slightly "artifical" / HDR look has something to do with the mystery. But it hasn't gotten me the way Dark has. I'll finish this one for sure, it does seem to pick up, but I don't think it'll be a rewatch for me (whereas I've rewatched Dark at least three times now).
