Let's face it, horror is probably the most controversial of movie genres because it tends to delve into the darkest corners of humanity. For me, it's among my least favorite genres because it's so seldom done well. It feels like too often horror directors will go for gore rather than genuine frights.
There have been a couple of successful scares — Misery and Blair Witch spring to mind — but for the most part, as a genre it doesn't really do it for me.
But Halloween is a bit different. The season just demands some spooky stuff, doesn't it? But what to watch? Well, for those of us with a complicated relationship with horror flicks, science has determined the absolute scariest horror movie of all time.
