I' m a coward with horror movies, when I try to watch them at home usually I finish keeping a pillow on my face and repeating no...no...no.. (fascinating, I know

).
So based on my very scarce experience:
Tesis- great movie, but it scared me only in the first part, then I was hooked by the plot
Society - (only 5 minutes... the wrong ones) Totally disgusting... and some people even paid to see it...
Ringu - Beautiful, the scariest film I've ever seen. My favorite in the genre
Profondo Rosso- Dario Argento's masterpiece.
The Call - full of clichés but with some good ghost scenes.
Les Rivières pourpres - Small French colleges can be terrifying places as well
The Fury - Poor Kirk Douglas...
The Hitcher - The scene where the girl dies every now and then returns in my nightmares...
