I just don't agree that mainstream media has to be simplistic and boring because the average American is too stupid now to handle anything different.
We literally just exited the "golden age of television" with shows like Mad Men, The Sopranos, The Wire, Breaking Bad, etc. These shows were highly rated by critics, and renowned for their risk taking and complex character motivations. The general public literally loved all these shows because of that. These all became money makers/cultural phenomena because they were challenging and different.
It's unfair to act like the general public can only handle Spiderman movies or CSI because they couldn't grasp anything better. They're not all morons
