It was watchable, but there were too many inconstancies and holes in the plot.
The dam scene in episode 4 was a real mess.
With Sterenn and Lyes approaching the scene, we see Markus removing a trussed and unconscious Marciano from the boot of his car and drag him over the road to the railings.
Only seconds later when Sterenn and Lyes arrive, and pull up shorter than they would in reality, we see that somehow Markus has manhan-dled Marciano over the railings and sat him on the edge over the dam. This is nonsense and physically impossible to manhandle a trussed body of the size of Marciano over metre+ high railings.
As Sterenn continues to talk to Markus over the phone, even though they are now within hailing distance, she fails to take the obvious action. This is to save Marciano by shooting Markus and thus solving her own complicity problem.
Of course dramatically this would have brought the story to and end and not allowed for further episodes, but it does make me feel that the viewers are being played as mugs.
The ending was poor and not believable.
