The series is cruel and very brutal but also has an (almost) romantic fairy tale atmosphere. Since the fairytale get you read in front go to bed in childhood was a creepy aftertaste. But the fascinating thing about the series is that it shines despite many brutal scenes and partly Horror similar scenarios by the very likeable detectives and assistants against evil. The story is very well thought out and throughout the series you recognize who is really friend and foe and who is pulling the strings in the background.
The series is made in my opinion, unique and awesome as it appeals to criminological, fantasy, fairytales, and horror film fans at the same time.
