As a kid, in the 60's....used to go to the afternoon features.
An italian or french film, dubbed, black and white, about vampires called "Black Sunday". Scared the shit out of me....I was like 7 or 8. Anyone heard of it?

I rate horror movies by many different categories:

Overall scariest when I first saw it: "Alien"

Best use of latex: "From Beyond"(one of my faves overall and John Carpenter's "The Thing"
Most gory scene: "Dagon" Spanish, rather new..I may have the name wrong, shows a guy get his face skin pulled up over his face.

Best vampire movie: I know I'll get flamed but: "Bram Stoker's Dracula" by Coppola. CLose to the book. Honorable mention: "Salem's Lot" Wish it was made for the theatre instead of TV.

Combo of gore and camp "Evil Dead" "Re-animator"

Best Werewolf Movie: "America Werewolf in London" "The Howling"

Best Frankenstein movie: "Frankenstein" the original 2nd best "Mary Shelley's Frankenstein" (with deniro)

Best Creature movie: "Alien" Hands down, scariest and best made though John Carpenter's "The Thing" was good

Best Ghost Movie: "Poltergeist" and a tie with "Ghost Story" (John Houseman, Craig Wasson Obscure film)

Best Slasher Original "Halloween" it set the std for many to follow. honorable mention to the first "Nightmare on Elm Street"

Best old time creature feature "Creature of the Black Lagoon"

Best old time giant creature from radiation testing ..I dunno, I liked "Them"

Best old time werewolf "I was teenage werewolf"

Best old time Scifi scary "Forbidden Planet"

Army of darkness scared the piss out of me
