This is just the current wave that Hollywood has decided to support and cash in on. Most of the content that comes out of the studio system are remakes. They are either official remakes in name, or rehashed plots from previous films.
Casting the film using the current wave, be it IR couples or LGBTQ angle, is just a way for them to put a new package on an old product and sell it to modern audience.
That's all it is.
Pretty much..
If people are overly influenced by media to the point it's factoring into peoples own personal decisions. That would be a family structure issue, and not Hollywood.. These people are chasing a bag, just like anyone else in the country..
