When I was doing the stage in Castenaso (BO) my colleagues use to talk me about Dexter.
Dexter is a tv series who talk about Dexter Morgan, a forensic blood spatter analyst for the Miami Metro Police Department who also happens to be a serial killer.
He was taught by his adoptive father, Harry, only to kill those "who deserve it"; mainly, other killers who have escaped the legal system or were never suspected in the first place.
Dexter's opening title sequence features an extended montage where ordinary day-to-day events such as shaving, flossing, dressing, preparing breakfast and eating are used visually to evoke Dexter's sinister nature. 
"The first time you see it... it tells you everything you need to know about the character."
