Go rent the Mike Judge movie, “Idiocracy,” from Netflix, or your local video-store (just not Blockbuster—they probably won’t have it since it has anti-establishment themes). It’s an insightful look into the future of Mankind (assuming we continue on our present heading into oblivion).
The plot involves an average moron from our time who is cryogenically frozen for thousands of years until he thaws out to find the world in ruins and disarray. Thanks to over-breeding by idiots, reality-TV and junk food, the world of the future is populated by mouth-breathing dolts (and if you find that premise far-fetched, watch this video).
Our hero then finds himself in the unenviable position of being the smartest man on a planet of morons. Hilarity, and more than a little despair, ensues.
