The dividing line falls neatly between the adventurous shows fielded by niche cable networks and the largely mainstream, predictable offerings from broadcasters.
"It couldn't be on any quality television." "
I'm sorry. Since when does a polygamous family and a meth-making school teacher qualify as "quality television"?
Apparently programs need to be "edgy" and "adventurous" to be considered quality television. Apparently the definition of "edgy" and "adventurous" is "sinful" and "illegal". If you're not, you're mainstream and predictable. How boring.
Now, admittedly, I haven't seen any of these shows since we don't have those channels. I am only commenting on the concept that if it is inappropriate for broadcast tv, it is more likely to be a lower quality show. I bet House, Lost, 30 Rock, and The Office would disagree as well.
