I don't think it's necessarily "lazy programing" more like opportunistic.
They know more than 1/2 the market share has at least heard of some dooms day prophecies and several point to this year.
So what better way then to help nudge ratings then to play to a subliminal message already circulating.
As far as anyone knowing anything.
From my experience if Hollywood knew anything we would already know.
Everyone would know.
Why do I say this?
I live in the famed "Valley", and know many Hollywood people.
From low level people to mid, to big wigs behind the scenes.
I've even partied with some of the famous actors and I used to bartend on Sunset, and other parts of Hollywood.
The one thing 80+% of Hollywood type people have in common is they can't keep a secret worth a damn.
I don't quite know why this is, but everyone I know from the Hollywood scene can't keep a secret.
As soon as they hear something they are just bursting at the seems to take you aside to a quite place and tell you they know something important, but
you must swear not to tell anyone ever.
Some of the secrets are so annoying and boring I have to fight the urge to roll my eyes back so far I have seizures.
Most make me go "eh", or "that's coo"
Some of the secrets are actual secrets that should not be leaked.
So if anyone in the movie/tv industry knew something was up we would all know in short order.
Oh and no, I'm not going to spill secrets to prove I know them
Who knows, something could be up, but Hollywood doesn't know about it that's for sure.
Oh and as far as disaster movies go, and how even the B ones seem to be eerily possible sometimes.
Studios have professors on their payroll from most of the colleges in So Cal.
These Professors had over their latest pet theories/papers, or even Grad Student papers that have the potential to be turned into a disaster movie.
That's why as lame, or out there as all the disaster movies are you can alwayse spot 1 or 2 things that make you go "huh that seems eerily
