6. Who Can Kill A Child? (1976)
Similarities might be made with another movie on this list, Don't Look Now, when it comes to the more obscure Spanish horror flick Who Can Kill A Child?, which shares a comparable tone (edgy, unnerving horror) and also features a couple who go on holiday to disastrous consequences. Who Can Kill A Child? is a far pulpier affair, however, but one that - thankfully - doesn't look to dodge the question in its controversial title. Had it opted out, it might still be a good movie, but its in Narciso Ibanez Serrador's willingness to take the plunge that his horror touches greatness. Who Can Kill A Child? follows a couple, Evelyn and Tom, as they holiday in Spain. They end up travelling to a remote island, devoid of adults, where the remaining locals - all children - have turned murderous. It's never explained why the children have resorted to such ways, nor is it necessary: most of the movie is slow and atmospheric, with occasional injections of terror, but it all builds to climax that is genuinely worthy of the film's title, in which the couple are forced to take action, shooting children dead in order escape. The point? What would you do, in their situation? Who Can Kill A Child? is great because it at least attempts an answer in its ending.
