Children: Murderous? Sometimes. Fanatical? Occasionally. Easy to batter? Always. Just why the two leads in this Stephen King adaptation don’t realise that children are the optimum size for a boot in the face is beyond us, but a lot of the kids in Fritz Kiersch’s 1984 Children of the Corn look like they’ve already taken a blow or two to the face anyway, so maybe that’s not the best way to correct bad behaviour in early years after all.
