1) Carry on Screaming - the fact that you could grow werewolves from severed fingers scared me so much as a child.
2) The Lost Boys - who says vampires need to be scary. Sometimes they just wanna rock out to Inxs and get juiced up.
3) The Grudge (Japanese version) - that low rumbling throaty noise that accompanies every sighting of the spectre is pretty chilling.
4) Blade - not strictly horror but anything with vampires and samurai-welding nutcases who don't do their taxes properly is alright with me.
5) Witchfinder General - quite chilling and full of boobies to boot, which made a nice contrast from all the gut-wrenching political evil and macabreness going on.
