The turning point in crime shows was when we began seeing the detective as a person. No longer was it the crime -> case solved straight line but we got to know a little about how the (imaginative) hero was as a person. Depths were added to the supposed reality of the genre. Nowadays it's standard.
What do you do, then, when you think the hero or heroes of a crime show are utterly uninteresting and superficial persons?
the road goes on
(“You stop watching those shows, don't you?”
“I'm not watching. They're just there, aren't they?”
“Well, you turned on the TV ... I rest my case.”
