Funny that the supposed setting for the series should generate more lively discussion than the show itself in the last two seasons.
If you wanted to, we could talk about the technology instead? How are they running those cars? Looks like petrol engines. There is/was Oil in Oklahoma, but do we see oil drums or pumps? Do they ever need to fill up the cars? How do they get parts?
Maybe they run them on electricity? They have electric lights and that machine that gives you the "Gift" lights up and has power gauges with needle dials. Where is that electricity from and how is it made and supplied?
And that machine that gives the "Gift" - does it look futuristic? It looks like a 1950's B Movie to me, or even a 1930's serial. It is electro-mechanical rather than electronic. I can imagine the Emperor Ming the Merciless strapping Flash Gordon to it. A couple of weeks ago someone broke it in a shower of sparks and cloud of smoke, but last week Pilgrim announced it had been fixed again (by that strange workman who just stands around doing nothing.)
If you wanted to, we could talk about agriculture and food supply. People cannot live on Poppies alone.
Let's face it, very little in this series makes any kind of sense at all.
