Here, for your viewing pleasure, is a shining example of the differences between American and Asian horror. A clip from the classic Japanese film, Kairo. Apologies for how dark it is though.
P.S. I did not make nor did I upload this clip though I wish I had on both counts.
First 3 minutes
Do you see how the woman quietly appeared in the corner, quite far from where he was standing? In an American film she would have appeared directly behind him accompanied by a loud sound. Notice how she slowly walked towards him? That stumble she makes is one of the creepiest things I have ever seen. In an American film she would have walked towards him then suddenly teleport forward a couple of feet,
Rest of clip
You might have to watch the movie to get what's going on here. (O___<) *wink*
Anyhoo- DO IT (ಠ_ಠ) DO IT NOW NOW NAO
Anyway @6:57 You can be assured that in an American film something would have startled her and you, the audience, when she turned the light on. The maker of this video was also aware of this convention.
A clip from the remake, Pulse, for comparison but not for pleasure.
Of particular note is the moment @1:27 when the thing with many arms jumps out at her. A typical cheap jump scare moment.
