For those who have read literary source material, Justified: City Primeval taps into the Detroit story and atmosphere perfectly, while introducing Raylan who was never a part of that original book. The novel itself was similarly smooth and crime-ridden, not fast paced, but very engaging just like this past season played out on its own trajectory.
Raylan, while older now and more refined, can't be compared to younger Kentucky Raylan and I think that's where some of the misinterpretation is.
In any case, this was a fantastic finale that connected both Justified shows while carving out more potential for an ongoing narrative. I'll keep spoilers out for those who haven't seen it, but this is flat out one of the best episodes of the entire show.
