I like this trailer because it is short and affective. It doesn't really give any hints or clues as to what the film story is or the outcome, this leaves the viewer wanting to watch the film to find out more about it etc. It also uses the background music to give a tense atmosphere and as the music becomes more upbeat the clips become quicker and also it becomes more tense/scary. This links to the films genre, being a horror film it will need to build up tenseness etc to satisfy the target audience who will be expecting the film to give this type of atmosphere. It also has a voice over all the way through the trailer that basically directs its speech towards the viewers. This makes the viewer feel apart of the film and become more involved within the trailer as if they are invited to go and watch the film. They also use a quote "shot in state of the art 3D". This also entices the viewer to want to watch the film as they expect the film picture quality to be very good and using the latest technology in film which is 3D.
