If you want decent horror films go to the world cinema section. The original The Ring was Japanese if I remember correctly. And REC is Spanish (Remake is quarentine(sp?))

I worked at hmv part time and I do mainly buy world cinema horror because it is a hell of a lot better.

It's not your birthday anymore but... I'll just say stuff anyway that about ten other people have said.

I must say, the remake of A Nightmare on Elm Street is pretty badass. Background about Freddy got tweaked a lot but it's really cool.
Paranormal Activity. It's really slow moving but the ending scared the shit out of me. I almost jumped out of my seat. (which says something because I usually just flinch when I get scared... or it says I'm going soft... anyway.)
Amtyville Horror
The Messengers was pretty good.
The Scream series

It really takes a lot for me to get scared over horror movies but the closest movie that gave me chills and had me scared pale was SINISTER!!!
That movie felt so real with the footage and the sounds *cringe* I'm getting chills just thinking about it!

The Conjuring
Insidious
Insidious 2
Sinister

Those are my absolute top 4 in no particular order.
