What is the scariest movie/s u have ever seen?

I haven't watched any horror film atau anything, but the scariest was probably The Disappearance of Haruhi Suzumiya. The part near the end with Ryoko...*shudder* Yesus Christ, she just flew up with a pisau and stabbed Kyon while getting all lesbian-like on poor Yuki, who was just kind of freaking out. DAMN, SHE SCARES ME lebih THAN RUSSIA AND/OR BELARUS!!!

I think it's 'Boo'. i was like 'it's not real,it's not real...it's just a movie' :D

i dont know, the 'Alien' series mabs? i get scared easily, but Paranormal Activity? Pelease! i was laughing!

Scream 1,2,3 and 4 r pretty freakish but not so scary as gorry

Human Centipede? Now thats just plain freaky, i only watched the trailer but its sooo disturbing!
