Maybe so, but even the G films are stupid and disgusting now.
Remember "Cat in the Hat"?
Let's be real.
Even the old Biblical epics were sword and sandal movies with some phony piety thrown in. Sword and sandal movies were about Hollywood showing as much bare flesh as it could get away with before nudity. The "piety" was so the Legion of Decency would not go ballistic over Gina Lollabrigida's costume. But once it was okay to show boobs, there was no reason to keep making sword and sandal movies. Nudity is the cheapest special effect.
The culture of Hollywood has always been bohemian and therefore intrinsically hostile to traditional religion. Pious movie stars (Deeply Catholic Loretta Young was nicknamed Attila the Nun. Marlene Dietrich sneered that the reason there were so many churches in Hollywood is that Loretta Young built one every time she sinned.) always stood out.
PIXAR Animation is a big contributor to this... Finding Nemo, Toy Story, Bug's Life, Incredibles ... all well-written STORIES with state of the art computer animation. I think each one did at least $300 million plus once merchandising is factored in.
