Mom And Dad (2017)

For reasons that I don't think are explained in the film, some kind of thought-virus infects the world (or at least the small part of it seen in this film) that makes parents want to kill their children, but only their own and in every other way act like normal well adjusted folk.

Kids annoy the piss out of me, so I think I may have already been exposed to a light dose. Don't get me wrong, don't wanna kill any of them, but I'd be happy if they all fucked off. Can't the rest of the world purchase Australia and turn it into a land where all new humans, up to, say, thirty years old, are placed?

Anyway, Nicolas Cage does his 'look at my wacky uncontrolled emotions' thing and various offspring get offed.
