I have noted the descent to the lowest common denominator.
The Nostradamus, Mayan prophecy, etc. Nothing like programs to scare the crap out of the masses to bring in the wide-eyed gullibles.
I'm disappointed to find that their supposedly scientific programs are without a lot of merit. Guess I'll limit myself to mostly PBS scientific programs. I think they still have quality.
OTOH, programs like the Black Hole thing do get my imagination to churning and that IS valuable. I'll just have to take it all with a grain of salt.
