The trailer shows that this is a crime thriller by the way it used certain narrative techniques with thing s such as restricted narration as we only see it as one main man murdering his wife and him being interigsted so he is the main character at the beggining. also protagonist and a antagonist used as the cops and investigators are the protagonist and the murderer is the antagonist. This text is a non linear text as it starts off with the man shooting his wife and this gives the an thought to the audience to why the wife was killed. Also uses enigma codes, action codes to keep the audience interested but the hostage situation with the police and the shotting sction between the protagonista nd the antagonist.
