ECU's are another common convention of horror movies, as not only does the camera shot allow you to identify with the victim, but the extremity of the close up also adds to the strangeness of the film, almost as if the camera shot is 'too close for comfort'. As you can see from the bottom picture taken from our horror film, having a close up to the final girl is asking the audience to relate to her, which coincides with the theory of 'the final girl' and also making it clear who the protagonist is.
