Horror is my favourite genre too and like a lot of you I've not been scared for many many years, I'll try and remember a few.
A girl walks home alone at night was decent,
Let me in,both versions,
Eden lake is quite good,
I saw the devil, decent,
Last house on the left,
Death note is different,
The host,
The visit was ok for a new film but could have been so much better,
Event horizon is a classic,
Audition,
Above as below was pretty good,
Duel, not really a horror but it's scary,
Hitcher, the original is a classic,
Wolf creek,
Joy ride is pretty good too.
I've seen hundreds of subtitled/non Hollywood films far too many to remember unfortunately .
