20 Most Underrated Horror Movies EVER

5. The House That Jack Built

It isn't hard to see why critics and audiences alike were firmly split on Lars von Trier's The House That Jack Built - a Serial Killer Movie that's basically a wilfully vile rebuke to the notion that films about murderers should be in any way entertaining.

Von Trier's gruelling 152-minute odyssey grants the audience little opportunity to relish its sadistic violence or find anything "cool" about the killer's quest, instead luxuriating in the abject ugliness of his existence and the miserable fates of his victims.

But it's also one of the most intoxicatingly visionary horror films of the last decade - at once a carousel of queasy blood-letting and a deep-dish spirit quest for Jack, played with Oscar-worthy nuance by Matt Dillon.

And yet beneath it all, the film's bonkers final scene proves that von Trier has a deeply effed-up sense of humour about his work, even if it leaves many struggling to decode precisely what he's trying to say, if anything at all.
