So according to TV Guide, Tom's Ghost *is* a vigilante action hero. Which I find hugely comical.
I get that the humans are "different," but they aren't that different. They can't be, given their lack of technology, no special powers and dwindling numbers. That's a central conceit of many sci-fi productions, that we as a species are somehow different, and it only works when we see how we are different. So far, humans are mostly dying and losing on this show. A few small wins, sure, as we exploit that alien arrogance. But not enough to be meaningful. And with this season premier, it became even worse. I don't see an end game for humanity without a convenient plot twist like a new weapon, a new alien race or a disease that kills aliens.
I just watched the season premier of Defiance, and that's what Defiance did. It closed last season with characters split up and opened with them in their new situations, and then reunited some of them. While I am not a huge fan of Defiance or Falling Skies (I love sci-fi though), Defiance did the season transition much better IMO.
