Se7en's Opening Credits

The opening credits for the film 'Se7en' contain a lot of the features I listed in my previous post, but displays them in an interesting way.
Between each of the titles flashing up is a small clip of the story that is currently happening, which enables the film to develop and give the audience a sense of what is going to be happening at the start of the film. The genre of the film is clearly identified through the font, which looks like a child's writing (clearly formed letters and not in a perfectly straight line) however the flashing/mirroring/movement effects used on the words is what most strongly shows the genre because it is a technique often used in thrillers.
There is a mix of the titles being on blank screens and being displayed over the film being shown, which works well yet it wouldn't be something I would necessarily want in my own opening sequence, but is a possible idea. There isn't necessarily a title with each new frame, but they come at regular occurrences.
