Am I the only one here who's absolutely sick of J/K-Horror? It's all pretty much exactly the same god damned movie, with a different scary kid, and the plot wears some different clothes, but, if you've seen The Ring, you've also seen The Grudge, The Eye, One Missed Call, and all the others... they just keep coming.
But on topic, I watch a lot of horror, as in, the vast majority of my DVD collection is horror, I watch it, I study it, I love it. And there really aren't a lot of movies that can get under my skin, but I'll mention the ones that get the closest.
Session 9: I'm actually saddened by how few people have ever even heard of Session 9, because while it may not be the world's most unpredictible movie, it knows how to scare. Session 9 features what I believe is the scariest moment I have ever seen in any movie. It's set in an old asylum, and the main characters are a crew who've been sent in to remove the asbestos from the ceiling. It's kind of a tride and true formula, but it's done so God damned well you can't help but love it. And if the creepy tapes don't give you the shivers, hopefully the chase at night, featuring one of the most terrifying sillhouettes I've ever seen will.
The Blair Witch Project: The good ol' Blair Witch Project has taken a lot of abuse in its days, and despite the fact that it is now viewed for the most part to have been little more than a pop culture phenomenon, I still contend that for consistent scares it's hard to beat. It is, unfortunately quite impossible to get the full effect of the Blair Witch Project today, but when the movie was first coming out in theatres, Sci-Fi channel ran a fake documentary about the Blair Witch, making it seem like the movie actually was real footage. For anyone familiar with the way that spectacular stories can spread as being true, it is not hard to imagine that a good number of the people who went into the theatre on opening day really believed that what they were seeing was actual footage of a supernatural encounter. Even without this added scare, however, Blair Witch's treatment of the monster is excelent, and really lend to its ability to scare. If you haven't seen it, give it a try.
John Carpenter's: Prince of Darkness: I am always amazed at the number of people who will mention The Thing, and even In the Mouth of Madness, but forget Prince of Darkness. The fact is that they are all part of John Carpenter's "Apocalypse Trilogy," and for my money, Prince of Darkness was by far the scariest. Perhaps it is my fear of sillhouettes (this instilled in me at childhood when I read my first horror book, a cheap alien pulp thing called The King of the Sun) but, it is the sillhouetted figure featured repeatedly in dream sequences throughout the course of the movie that really gets to me, gives me the chills. Add to this one of the best ever "thing with a creepy voice" scare, and a really really cool big glass tube of spinning green liquid, and you're in for one hell of a ride. If you're a Carpenter fan, give Prince of Darkness a try.
Honorable mention today goes to...
The Mothman Prophecies: Mothman isn't a straight up horror picture, and again I think its the dark sillhoutte-ish forms that get to me. It is based (quite loosely I might add) on a book by the same name, written by noted UFOlogist John Keel (which, personally speaking, I find much scarier). Note here that the movie omits the entirety of the UFO phenomenon from the plot, changing Keel from a paranormal investigator into a news caster. Long story short, Keel does claim that the events of the book are true (some of them, the collapse of the Silver Bridge for instance, are actual historical facts, but for some things you will have to choose whether or not you consider Keel and his various eye witnesses to be reliable reporters). A little more internet investigation will lead one to a wealth of "case studies" (in really big quotes) from various Mothman sightings around the world. It is perhaps just the idea of the phenomenon that I find scary, but for the most part the movie captures that well, and if you think about it when you get up for your midnight bathroom trip, you may find yourself wanting to turn on a few more lights.
