At first I was somewhat excited... hey new premise, SF... Whoo Hoo! But I could not suspend belief long enough.
The idea behind this show is that somehow all electricity suddenly doesn't work... and then they jump ahead 15 years later.
So right off the bat I am thinking, hey 15 years is enough time to have developed some crude industrial processes... based on the industrial revolution of the 1800's... and steam power. But they have only shown agrarian villages so far, as if everything having to do with steam and natural gas have been totally forgotten. But how can that be, there are working steam engines in museums and on RR tracks and even in older Navy ships... it's not as if it would be impossible to put these to work.
But somehow all that stuff has gone the way of the Dodo bird.
I can only suspend belief so far.
