10 Horror Movie Villains Who Were Totally Right
5. The Intruders - Knock at the Cabin
M. Night Shyamalan's Knock at the Cabin revolves around a family who are terrorised by a group of four strangers at their remote cabin getaway, who inform them that they must sacrifice a member of their family in order to prevent an impending apocalypse that will wipe out humanity.
As the tense hostage situation drags on, we see more and more suggestions that the end of the world is indeed looming, though of course, we can't ever be sure that this isn't a giant hoax on the part of the quartet - this being a Shyamalan film and all.
Ultimately, one of the family, Eric (Jonathan Groff), becomes convinced that the intruders are correct, believing them to represent the Four Horsemen of the Apocalypse, and so willingly allows himself to be shot by his husband, Andrew (Ben Aldridge).
At this moment, it's confirmed beyond any doubt that the intruders were telling the truth, and that a series of calamities did indeed take place, but were stopped the moment that Eric laid down his life.
That is to say, the four antagonists were absolutely 100% in the right. Forcing someone to die for the sake of the wider human race was a utilitarian move rather than an act of evil, as horrifying as it still was.
