Analysis of 'The Girl with the Dragon Tattoo' opening sequence

In the Opening of 'The Girl With The Dragon Tattoo we first hear non- diegetic sound,with a black screen, this grabs the attention of the viewer. Images and text then begin to flash onto the screen, this is effective as it gives the viewer a feel of what the movie is going to be about, if the images and text had faded into the screen we could have made the assumption that the movie was going to be of a different genre to what a movie with flashing images could be. The viewer sees many different images that at this point don't seem to be of a particular thing, the colours are mainly blacks and greys and we see a black liquid kind of thing which seems to be covering other objects, a kind of suspense and curiosity is created at this point, as the viewer is left wondering what relationship these images have with the rest of the film. Also the colour black could symbolize darkness or danger.
We then see the title of the movie appear on the screen and the black liquid kind of 'hits the words' and covers them up entirely. the sound (non - diegetic) has been playing the entire time, from start till now, and at this point the sound appears to be getting louder. The sound is the 'Immigrant song' by Led Zeppelin.
At this point the viewer can make out the image of a person struggling, also surrounded by the black liquid. The camera seems to be following the black liquid and is going wherever it goes, sometimes there are even point of view shots that make the viewer feel like they are the black liquid and they are the ones surrounding words and on keyboards etc.  We then see fire, which could also symbolize danger, or an element or horror. As the sound speeds up, so do the images as the flash onto and off the screen.
