I saw the first two episodes on a flight two years ago and it struck me as quite wacky and worth seeing more of: it's about about a post-apocalyptic USA after a virus pandemic. I've tracked it down in recent weeks in various places on the net (and I notice that it's available via Amazon Prime) and it becomes increasingly oddball as time goes on.
I'm just about to start the fourth (and last series) and it's very oddball but, for this humble soul, very entertaining.
