Analyse the cinematic techniques used in the "Exorcism Of Emily Rose". How do these techniques reveal concepts of justice?

The Exorcism of Emily Rose (2005), directed by Scott Derrickson, has elements of a number of genres, however chiefly it could be classed as a Horror/Mystery/Thriller. The main tagline is 'What happened to Emily?', suggesting that the viewer will be making up his/her own mind in relation to the events portrayed in the movie. The movie stars Laura Linney, as defence lawyer Erin Bruner, an agnostic who represents Father Moore (Tom Wilkinson). …

…as opposed to medical views which seemed to be more accepted in the modern society. It explores deep legal and ethical issues, and requires the viewer to engage their brains and make up their own minds as to whether Father Moore is guilty or not guilty, and therefore whether they are questioning his intent. It developed my understanding of justice through the exploration of different viewpoints and how personal beliefs can heavily affect ones actions.
