London To Brighton

the use of enigma in the title sequence makes the audience want to carry on watching and wanting to know what is going on. 
The women with all the bruises and marks over her face makes you wonder why she has this and who has done this too her, you also want to know who she is running from. The fact there is a young child with her on the run as well who has make up on her face makes it more disturbing. You also want to know what the relationship between the young girl and the women is we don't know whether they are related or not. 
The setting of the bathroom in the opening scene is very dirty and not somewhere you should take a child. The scene of the girl waiting in the cubicle on her own is very effective as it shows how scared and vulnerable she is this makes you feel empathy for the child and know how frightened she is. 
When it shows the women going out to find money by selling herself makes you also feel sorry for the women and shows the darkness of the film and how she struggles to get by. 
On the train you see a more caring side to the women when she comforts the young girl and is there for her. It also makes you wonder why they are leaving. 
This opening sets the genre of the film that it is quite disturbing and upsetting, it also gives something away but not too much so they want to keep watching.
