This is now my third attempt to write a review (and it will be my last).

Episode 1 to 6: 10/10 - GREAT
Episode 7 to 12: 0/10 - TERRIBLE
Episode 13: I will not bother watching this mess any further.

For the downfall of this series mostly the bad script is to blame.
This makes a rating of 5, I guess.

My review must contain 500 characters? Very well. Everything that made this series enjoyable and unique got lost in the second half. Not even the acting was good anymore when it was one of the strengths of the series.
