For some reason I only caught up with this last week.
Have to say I was very disappointed. Not sure if I had wrongly remember the first series, but this one seemed to have lost the representations of the culture and setting it happens in.
And that whole sequence that seemed to go on forever of 2 men stranded in the desert being endlessly violent I just found pointless.
I'm sure in the first series there was more air time for members of the community - and his long suffering wife.
