I also enjoyed Night Country.
Season One was another animal entirely - maybe the best thing I've ever seen on TV. Certainly up there with Homeland and Sopranos.
After a disappointing sophomore effort (to me), Season Three brought the series back to the head of the pack. Season Four, while falling maybe just a bit short of One and Three, keeps the series as a whole firmly in the upper tier.
I know this - I sure am hoping that there are more seasons in the works.
