On those shows, how often are the criminals muzzie or dot-head?
Like I said I don't watch them if they show the usual signs of being about some horrible perverse crime or have a detective with supernatural powers because he licked a car battery or whose family died before his eyes in a tragic blancmange accident so I can't really say. One thing I have noticed is if they have a minority villain they are sure to have a minority good guy to counter-balance.
Why can't people kill each other for money or sex or revenge any more? I suspect it's writers who can't come up with interesting plot or characters and use horror in the hope of distracting you.
