Both are mystery series, meaning you need to pay attention and fit all kinds a clues about events together.
They both have a very creepy atmosphere during the night which enhances the feeling of being kept in the dark (I don't mean that literally).
Both series manages to joke around despite the seriousness of the pretty intense storyline
