"What should be" is so far from "what is". TV is about ad dollars. Most Americans think that anyone with a "funny accent" is either not worth the effort or a terrorist. As a result, to increase ad dollars, network shows in particular are a watered down mess. I'm impressed that the American "Office" is as good as it is; mostly the lowest common denominator's not going to allow that to work out.
It's just a theory, but look at what gets popular, and it's pretty easily borne out. There are exceptions, of course; they are what makes life worth living. But the crap to gold ratio's about 8 or 10 to 1.
As of today, three of the ten most popular movies are The Love Guru, The Happening, and Indiana Jones.
Three of the current ten most popular TV shows are Two and a Half Men, So You Think You Can Dance, and Million Dollar Password.
Three of the current top ten CDs are by Disturbed, Jewel, and Journey.
Take it for what it's worth, I guess, but any crap that appears on the charts are right in my wheelhouse of "things that I can easily believe".
