I'm sure the solution will be to make all these former children's characters sufficiently grim and moody to deal with this.
If I was in charge of a film like this (lets say a Captain Marvel film) I'd open with a disclaimer - James Whale's Frankenstein or La Belle et la Bete
style!.
In front of a lowered theater someone sets up and addresses the audience with a speech along the lines of...
"The film you are seeing is based off stories written many years ago, when children had to decide whether their ten cents would buy them candy or a comic book story featuring their favorite hero. They were written by men who were largely underpaid and almost wholly unappreciated - many weren't even credited with their work. But on those often blurry pages of newsprint they turned out stories of unequaled imagination and entertainment. The story you're about to see is outlandish, and bears only a cursory resemblance with the real world. It features men and women who say things real people would never say, do things that real people would never dare to do, and experience adventures that real people would never imagine themselves experiencing. I beg of you to turn back the clock and become a child, and accept the child-like simplicity, embrace the logic of a dream and always remember the magic word -
Shazam!"
.... hmmmm, wrote that in five minutes.
