Site ranks movies by scariness

Reelscary accepts public votes on the scariness of films, divided into three different genres of scariness: disturbing, gore and suspense.

1979 classic "Alien" is currently leading the suspense category, with 2008's "Martyrs" taking the gore honors. Hopefully, there'll be sections for books, games and TV shows soon.
