Bottom line, Hollywood is risk-averse. Find me a show on television or a movie in current production, I'll show you something that has been done to death already.
I'm hard pressed to find anything produced by Hollywood by a major studio in the last 30-plus years that has any originality to it.
Hollywood has been the top place to push propaganda from the government since the 1930's
I found this out watching the oldies channel and westerns from back then. Old Roy Rogers movies that pushed socialism, [ Rail Road needed farmers land to put a rail in, the farmers needed to give up their land at no payment for the national good. ]
On and on through the years, WW2 era most movies had a America against the Axes theme.
1950's movies and TV shows had the woman getting out of the work force to return to becoming homemakers so the returning GI's could take their jobs. YOU KNOW, WOMAN WAXING FLOORS WEARING HIGH HEELS.
1960's we were pushing the space theme, all the sici-fi movies and TV programs of that era.
1970's a big change, no war movies but the Green Berets, a play down on that Asian War.
1980's was all about distraction, music and dance.
1990's nothing I can remember.
2000's lots of kung fou and tear jerkers.
2010, lots of fantasy and horror, the nation went wild on CSI and true TV.
2011 A love affair with Vampires and Zombies.
It is true for the past two decades I was too tired from working 50-60 hours a week to watch much TV, only movie in that span I went to was Snakes On A Plane and Natural Born Killers.
Reality has become too uncomfortable for the public, were I a producer I would be digging into the disaster of that Russian Sub, the one on fire today and yesterday. Was it the rubber coating that caught fire, the anti sonar stuff we use on our subs???
This would make one hell of a movie, but, more people would rather watch Vampires, Zombies and prefer to go into La-La land then pay money to see reality????
But is that not what the movies are for, to take people away from the reality of their lives and transport them to another world, place or time.
Just watch when the movies shift to another theme, betcha the new ones will be back to space travel as the Chinese gain on us as we in fact have thrown away what could have been our claim to space to for some reason anyone country or big business to get out there ahead of the rest of the world.
