Codes & conventions and purpose of title sequence

Codes and conventions play a key role in establishing a particular aspect of a film and help the audience to thorth-willingly understand what genre a film is. The most common types of codes and conventions are mostly recognisable in horror type films as they mostly portray the traditional traits such as;

The rule of 3- whereby there are usually 3 incidents and most of the time 3 main characters that last longer than the other people.
The virginal character usually survives amongst all odds, this displays purity and genuine characteristics.
All blond woman are usually the first to be victimised and therefore is an obvious code of horror movies.

The reason that title sequences are used is to display who will staring in the film and to credit the production team actually created the film. The other aspect of having a title sequence is that it can give a brief synopsis in some cases teasing the audience in-drawing them into the film alongside giving minimal detail about the narrative and story away as possible.
