Great five episode arc, but with a weak climax.
I know the children screaming in unison was supposed to be a "Gee, the answer was right in front of us all the time" resolution. But I don't think it worked. It just wasn't cathartic enough.
It was weaker even than the Slim Whitman "Indian Love Call" resolution in "Mars Attacks!"
What made Children of Earth great was the expose of how our "leaders" would sell us down the river in a heartbeat if push came to shove.
