There appear to be two types of children on sci-fi telly: adorable, mop-haired tykes who need to be protected and saved from the bad guys, or evil little gits who want to suck out your soul. There’s probably a psychological side to this trope – parenting worries; the perverting of the innocent; fear of things smaller than we are (okay, we made that last one up). But either way, kids can be really bloody scary…
Doctor Who “The Empty Child”
Excuse us while we crap ourselves.
Honourable mention: The Twilight Zone‘s “It’s A Good Life” features a little kid who can control the universe with his mind. He also pops up in the Twilight Zone movie with a giant rubber rabbit that still haunts our nightmares.
Supernatural “I Believe The Children Are Our Future”
This episode introduces young Jesse Turner (Gattlin Griffith, who went on to play young Ryan Reynolds in Green Lantern), who can make things happen just by thinking about them – for example, turning the angel Castiel into an action figure. Clearly he’s evil. And yes, as the episode progresses, we discover that he’s actually the Antichrist himself! Dun dun daaaaaaa!
…At which point he goes on holiday to Australia and has yet to return to the show. Like, what? You write in the Antichrist and then he simply buggers off? Rubbish!
