This show demonstrates a serious lack of consistency which makes it only mediocre on balance. It delivers great and crummy scenes
In sequence. Here is an example:
The final episode of the second season includes intense and deep dialogue between the two primary protagonists with insight into the secret nature of serial killers. It is really creepy and really good. The very next next episode opening the third season is slow and moody and boring. It includes lots of brooding looks from actors with an ominous soundtrack. The writers and directors and actors came across as lazy.
