10 MORE Horror Movies That Tricked You Into Rooting For The Monster

1964's The Last Man on Earth was the very first adaptation of Richard Matheson's post-apocalyptic horror novel I Am Legend, and remains the only one to fully engage with the notion that the human protagonist is very far from a hero.

We naturally spend most of the film fully behind Dr. Robert Morgan (Vincent Price) - the apparent sole survivor of a plague that has turned the rest of humanity into a fleet of undead, vampiric creatures, which Morgan systematically hunts and kills.

But at the movie's end, Morgan learns that a vaccine has been developed that helps keep the infection at bay, and many of the "creatures" he's murdered throughout were actually sentient humans. More to the point, Morgan's murderous ways effectively cause said humans to view him as the boogeyman himself.

This reveal so perfectly exploited humanity's solipsistic assumption that they're the default "good" force in the world, and anything vaguely "other" must be bad - even if it's actually still human.
