I will chime in by saying I did like this show, but the rushed plot lost me a while back. I did watch season 2 ep 1 and thought it more of the same. I understand that they rushed the plot because they were worried about being cancelled, to try and finish the story, but it didn't work for me.
The whole premise of the story was great. The idea of the single town, completely in the dark about what was happening in the world, desperately trying to make it on its own, was great. But they gave away the mystery too quickly. It should have taken many seasons for the government to get re-established..........I'll still likely watch it but its lost its initial brilliance for me.
