The visuals, the actors, the production design and the score/soundtrack were impressive throughout the whole series. The slow pace adds to the mystery just like many of the emotionless dialoges.
But why on earth is it necessary to put a cliffhanger at the end of every series' season finale nowadays? Especially when it's not for certain that we'll get a second season. For once I'd love to watch a series with a proper ending. A really good production doesn't need gimmicks like that.
So sad, since 'Hausen' is something special indeed.
