Falling Skies was chief on our list, with Moon Bloodgood (whom we loved in the show Journeyman, which only received a single season) and Speilberg producing. We were not disappointed.
The show explores humanity in the backdrop of anarchy. The hopeful have banded together under a militaristic banner, the disparate and barely connected arms of a rebellion. The leader of the 2nd Mass is a retired soldier (I am forgetting if he actually made general before the aliens came), and his 2nd in command is a history professor, with three sons.
The prof, played by Noah Wyle, lost his wife in the initial attack and is doing everything he can to keep his family together. The first season his main quest was recovering his middle son from imprisonment/enslavement with the aliens.
The prof was the hope of the group in season 1. But all hints of what is coming after he has returned from a very traumatic encounter are indicating that he is turning cynical and he and the general are going to shift rolls within the group (though I doubt the hierarchy will be altered).
Ok--I am trying not to give anything away, look up season 1 if you haven't. If you stopped midway last season, I just want to say it gets really good.
