I would suggest trying Vikings (if historical/period shows is your thing). It’s on the History Channel but surprisingly good and definitely a lot more historically accurate than things like The Tudors or The Borgias.loving the americans and the following, haven’t heard of the other three, worth checking out??
Banshee is good as well, less character driven but I love there the plot moves forward, and at a fast pace with twists that keep you guessing and there are good action scenes (kinda reminds me of Nikita) - overall it doesn’t take itself too seriously which is always good. Should note there is quite a lot of sex - the explicit cable kind.
Top of the Lake only actually just aired but it has Elisabeth Moss and what I’ve seen so far looks promising - I just hope the case actually gets solved unlike The Killing. The cinematography is amazing as well.
