Analysis of Brick- is it a good opening sequence?

Is the opening sequence to Brick a good opening sequence for a thriller?

As a title sequence for a thriller it includes everything it should do which is why I believe it is a good opening sequence. It is very slow paced which acts as a hand and leads the audience into the film and also gurantees that the viewers are settled before the real action begins. The information that the audience need to process is easy and isnt too fast so they miss out on any major parts which makes it easier for the audience to understand the basis of the film. Most opening sequences familarise the audience with the scenery that surrounds the character at the beginning and Brick is one of these. The viewers first see a dark tunnel with small amount of running water where a dead female body lies. The fact that there is a dead character already conveys to the reader that the genre of film is a horror, but it could also spark questions that the viewers may want to ask. The film establishes a certain mood by showing the shot of the boy crouching over adjacent to the girl that has been found dead. It shows to the audience that the female character must have been in danger and the person that killed her must be a violent and aggressive character to be able to do something so gruesome as that. As the viewers do not know who killed the female- they may question the young boy kneeling beside her. Was he the one that killed her? Or should he be careful as this may happen to him at a later date? The music soundtrack that is being played while the shots are shown has a very slow tempo and is at a low pitch which oculd represent the death of the female as low pitched music is represented with melancholy moments of time. The music has a feel to it that makes the audience seem uneasy about what they are going to see while the soundtrack is being played.
