When I read the Wiki page on Under The Dome I don't recall the butterfly shit being mentioned.
There was no butterfly, no "monarch", no egg/mini-dome, and Barbie was a hell of a lot more of a mystery.
I'm hoping the military searching for Barbie holds the one Colonel or whatever rank that Barbie knows quite well and work together.
I'm also pretty sure Junior was never anything but a pain in the ass, as in, was not part of any inner-circles. The children seizure thing and connection to the dome was a big part of the end-story.
I don't think anyone saw visions of other people, and the entities behind the dome had no interaction with the victims, and had no intention of "helping", until the very, very end.
I'll watch Season 2 when it comes around, just to see where they take this. I'm enjoying seeing some elements of the book presented on screen, but it's also it's own story. I definitely enjoyed the book, cover to cover, and enjoyed the book's ending. I felt there really wasn't any other way that story could conceivably end.
