The horror opening I have decided to analyse is "The Ring"

At the start we see the girl in a skirt and white top, this could be implying that she is still in school, but possibly in the late teens by how high the skirt is (she is more daring and provocative as she is in the higher years). The White top attracts attention of the simplicity of what she is wearing, which could make her seem innocent (although that does clash with what I said about the skirt). This, along with the provocative skirt, and the bare legs, can all lead to her being the victim, and her being vulnerable.

Next, all the rooms in this house are dark, this plays with human fear, of something we cant see killing us, but the part that makes this scarier is the fact its set in the house, something that nearly everybody has. Because of this, people cant differentiate between themselves and this character, making it alot scarier.

Finally, The opening of the fridge, or the TV turning on and off makes the audience feel something else is at work. Something more spiritual than what we've already seen, this causes the audience to get worked up, putting them on the edge of their seats, then we finally get  to that last scene, and we see a glimpse of the horror that can truly happen, putting that build up, to its maximum effect.
