Which film makes the biggest impact to the audience?

I think that 'Ghost Ship' has a huge impact on the audience, as your initial feeling about the film is that it is going to be romantic and a chick flick with the woman singing a calm and relaxing song, the setting is set in a ball where people are dancing and dressed formally and the camera zooms out and it shows everyone dancing which gives a 'warm traditional' feeling in which you do not expect something bad to happen.
Then the audience is introduced to the setting which is set on a cruise which makes the audience think of 'debutante', which is a daughter of an upper class family who is a newly adult and shes introduced to a formal society to show her 'new' image.
The camera keeps on zooming on to couples and the singer. The camera is also reverse zoom to show the couples dancing for no longer than five seconds. The camera shot then is a close up onto a young girl who does not seem to be enjoying herself, the audience wonder why she is not enjoying her self and why does she seem to be the only young person there.
One of the crew then asked the girl to dance but the music is still playing and you do not hear them talk which I think keeps the audience more interested as you can interpret there conversation however you want.
This is when the audience become alert as the shot changes into an extreme close up of a poll which hold the light wires together and it becomes loose and cuts off then suddenly the lights explode and the camera shot is pan shot follow.
The camera then zooms out which I think keeps the audience alert as the audience gets disorientated, as the camera zooms out and everyone gets slit in half and fall to the floor except the girl who the man she was dancing who protected her, this makes the audience know that this is not the film that they expected and that it is gruesome and a horror film.
This will stick into the audience minds throughout the film as it was a huge twist and makes the film more interesting when it changes onto the present day where the 'Arctic Warrior' ship needs to be repaired which gives the impression of a thriller film and keeps the audience on edge as they wonder what happened to that girl and will they survive but they do and a man in a pub tells them about the boat with a girl and it is of the radar everyone around the table looks worried, interested and tense and the audience are already glued to the film as it is so intense.
Ghost ship is memorable to the audience as there was a twist already and the sudden gap between the two different time periods make the audience interested.
