Just finished watching second series and I can see they've set themselves up for a third series. I won't spoil it my explaining who survives.
Like most good drama they invest in characters then dispose of them whilst keeping enough to preserve loyalty of the audience.
Still the high production values and morally ambivalent characters. Still fast moving with regular cliff hangers.
Plot does continue t involve considerable suspension of belief and barely credible death count but it s forgivable as being an antidote to American Formula cop shows.
