Structure to a thrillers opening

The four basic structures to a thrillers title sequence:

• Narrative opening with titles running throughout
• A discrete title sequence
• Narrative opening with titles running throughout
• "Stylised Editing" it is a mixture of the first two
• Titles over a blank screen, followed by the narrative opening

Se7en

From watching the title sequence of the film "se7en" it is clear that it is a discrete title sequence. There are no narratives and also there are a lot of ECU's, by using the ECU technique we (Audience) can only see parts of the main focus i.e. scissors cutting out photographs, part of the newspaper and we can see the hands of a person but not the face. 

I liked in this title sequence a number of things firstly the combination of music in the editing "drums and sounds that you would find on a keyboard",  this determines that the sequence is a psychological thriller.
