As always with shows like this, the first season was great - interesting characters, coherent plot, good tension and organic stories. I enjoyed it very much, it was truly atmospheric.
And like always in shows that only planned to have the one season, in the very first episode of season 2 it all went downhill - the characters from the first season were retconned, the plot became incomprehensible and convoluted into losing all sense, the characters became generic nothings that I couldn't care less what happens to them, it's as if in the quest for escalation, they lost sight of the down to earth approach that made the first season good.
And as always in these instances, there was no need for graphic sexual violence to depict how bad the bad guys are, season one accomplished that perfectly.
I'm not going near the 3rd season, it's going to be more of the same nonsense.
