Nearly all of the shots used are close ups often showing the person in distress or close ups showing the person being set on fire or chained, which helps to signify to the audience that not only will violence be one of the main themes present within this film, but also most likely some form of torture as the close ups present the isolated character as helpless. The dark lighting emphasises the dark and sinister themes of evil which are a common convention in thriller films, along with the use of the colour black. We also hear the use of an effective soundtrack in the background in which the long screams are used to effectively resemble those of the black character in shot, which backs up the fact even more that they are being made to suffer. We also see a mid shot of a skeleton on fire which often hints at death being a strong theme of the film.
The lack of light around the character presents her as vulnerable and isolated, and the shots of her getting sucked into the black liquid and drowning under water emphasise the overwhelming situation and perhaps the lack of hope that the character has in terms of survival. The editing is also of a fast pace which hints at the fact there will be lots of suspense, violence and plot twists witnessed within the film, and when all of these factors are combined they help to set a definitive eary mood for the film which is similar to that in most thrillers.
