Spielberg's new show Falling Skies may be much darker than we anticipated. Watch this five-minute sneak peek (which was shown to the crowd at WonderCon) of little kids drawing pictures of how their parents died in the alien invasion. Chilling.

The more we see, the more we're starting to warm up to this post-apocalyptic alien-invasion series. Falling Skies will be out on June 19th on TNT.
