Quite why this has been cancelled, I have no idea!
The premise is simple, a serial killer on the loose and a two focused plot on both the killer and cop chasing him/her! Sounds simple, but made better. Why? Because it doesn't try and complicate the story with interwoven plots (yes, true detective I mean you!), because it is set in an era when serial killers started to gain notoriety, because it doesn't shy from the gruesome aspects of a serial killer and more importantly, that sets it aside from true detective, it gets into the mind frame of the sociopath quality (yes I wrote quality, as its the one thing that sets us all apart, be that bad or good!) of manipulation and total confidence in the act by the said sociopath.
The casting is great, not newbies, but not stellar casting, this makes it convincing from an actor point of view as there is no cheesiness and its believable, the story is really well written, simply because it focuses on the main subject and rarely deviates from the chase, and the setting of the 70's for me at least, means the genre is right at the heart of the time when serial killers started to attain focus on what they did.
In all this is a cleverly scripted TV show and could easily have gone on to spurn multiple series, but for some reason it was cancelled, some cite the brutality of it (it's not that gory), but I expect it's because it's so similar to True Detective, but was made on a lesser budget with less well known actors, that was it's downfall. None the less, this is a well made TV show and deserves a second chance, but only if it is in keeping with what it set out to do...Tell a good story, with no over dramatisation, and using the simple basic methods of script writing...Keep it simple, make the plot believable, and keep the viewer hooked! I am hooked!
