The analysis of the opening of seven

The opening of seven is very good but confusing as it doesn't give much away so I do not really know what the story line is or what is happening. The use of soundtrack in the opening is very heart-pounding and creepy. From the soundtrack of the opening you can tell that the film is a thriller/horror film because it has all the elements of what  the soundtrack of a thriller film would have i.e. it creates tension and suspense, it sounds quite dull and it creates attention to the audience.
The use of digetic sound is used a lot and quite well in the opening, there are sounds like creaking and crackling which is sometimes used at points like when something is being opened or equipment is being used and some of these digetic sounds you can hear in the opening is used to resemble the use of equipment.
In the opening you can only see a persons hands and fingers which I assume are the hands of a killer or someone who has committed a crime and this is because the person does things that are not normal and seem like the person is up to something, for example using a tool that peels of his skin and his hands are quite dirty with bandages on them and he has repulsive images of a person with a tool in there head. Also the fact that we cannot see the face of the killer but only his hands makes the character look quite suspicious. Also the use of editing is good and has been used a lot , it actually looks quite clever because they have edited it so there are flashing images and once something has flashed another image comes up or the opening titles appear. They have also edited it so that images appear very quickly, for like a split second so that it looks more creepy and effective.
When the opening is being filmed the camera does not really move and they are always close up shots of nearly everything which is done for example there are close up shots of the character putting thread through a needle, cutting up pictures and when his writing and i think there are a lot of close up shots of his actions to give the viewer a bit of a clue that this is what the character does and to get the viewer questioning and trying to figure out who this character is and what he does. There is also an over the shoulder shot of the character writing in his book which is effective because it gets the viewers wondering what he is writing in his book, why is he writing what does this all mean and etc.
