I'm trying to keep everything vague enough for those that have not seen it yet, but I may fail so be warned before reading further.
I enjoyed the dark vision of the future and think everything depicted is within reason for the future... especially the law broken in the very beginning.
I also get why they focused on the teens later in the show, to view the "new" world with young eyes, but it came across pretty flat for me. I think I would have enjoyed more their settlement visibly struggling to survive and a more realistic approach by having main characters more hands-on (even w/tools from the future). The plot with the son did not seem like something a struggling, fledgeling civilization would allow (hey new guy, you can go play while the settlement still needs to grow and hunt our food

).
Honestly, I would rather see the leader's first days there. But in the end, I think the show has a lot of potential, if they can just find their footing... early!
