An opening sequence in a TV show creates an atmosphere which makes the watcher want to continue on. It draws the audience in and leaves a question in their minds, "what happens next?"
For example, the opening scene of the show where the people are fighting on the beach and when the police man tries to break them up, automatically we are left with the question, why were they fighting? Who is the police man? What comes next?
The opening sequence was very intense and the audience are deliberately left confused and intrigued to the plot.
In the title sequence, the naked people fighting on the beach show the class of the area and tell us instantly before the actual plot emerges that Brighton is quite a brutal place.
Different characters come out in different parts of the episode and this helps draw in different people towards the show with different interests and different opinions about what they want to see on the internet. For example, the man who stabs the Indian man appeals to people who like violence on television.
I think that the idea of cuffs is quite adult and the themes of the show should mean that it is after the watershed, no child under the age of 12 should watch it.
