I never saw a clear political bias in this series* however I have found it unsettling to see the US flag used as a symbol of evil.
At the beginning of S2 there seemed to be some connection with the Illuminati but that was never developed.
If they don't explain everything in the finale then I hope they publish a complete explanation post-mortem.
In contrast I've mostly lost interest in the issue of whether the power can be restored.
*I think they hoped to appeal to both sides of the political spectrum, as Hunger Games has done successfully, but mostly what I've seen are mixed messages.
