textual analysis of TV dram sequence 'Dexter'

Sound:.............> foley sound are sounds thathave been exaggerated to create a tense effect for example; when Dexter shaves you can hear a loud rough sound as he drags the razor up his throat. There are also non-digetic sound which we can hear but the characters can't like the theme tune but there are many digetic sound which the characters can hear like the sound when he shaves,cuts the meat and grinds the coffee beans. the theme tune is very strange and suspicious even though it is up-beat it still make you curious about the show.
