Conventions of HORROR films...CAMERA ANGLES!

The camera angles in the movie openings, i have found to be different all according to the type of horror the film is. However i have found that most films use MS (Mid Shot) as most of whats being filmed for the beginning is letting the viewer know the basic story plot of whats going on for example in the film "IT."
Furthermore in the same film the directors use a lot of worms eye view shots throughout the opening of the film. I think the director uses this as it's as if the little girl was looking up at it herself to make the "IT" seem much bigger and scary.  

However in the film "Halloween" there were a variety of camera angles different to many other films. In the opening scene you see it through POV(Point Of View) as the young boy in the story first of all just a POV shot but then he puts a mask on and you see it still as a POV but the viewer is limited on what they can see. After he kills the two people it then walks outside, the camera cuts to a MS (Mid Shot) to show the boy with the knife and the police officer. This makes the viewer shocked as they don't know who's view they've seen it from and cutting to a new shot showing a little boy with the knife creates shock for the viewer. 

As aposed to the others; the film "Se7en" uses a different variety of shots. The shots used in the beginning of this scene are ECU (extreme close up) and CU (close up) the shots used in the scene as well are really bizarre and interesting.
