unfortunately, horror movies pretty much suck nowadays. or, maybe it was just that i was naive enough to be duped into those "horror" worlds when i was younger and now, as a realist, i see through the hollyweirdness of it all. for what it's worth, i think the last "scary" movie that actually got my heart rate up was the japanese version of "the ring" and even that was a stretch.
enter the interwebs.
if you REALLY wanna scare the shit out of yourself, follow this plan:
turn off all the lights. throw in a dark soundtrack (i personally suggest hans zimmer's the dark knight; start at the very beginning and let it play through). then read, from start to finish, ted bundy's wikipedia page.
i guarantee you you will jump at least once.
