Just curious...could you give some examples of films you feel fit that definition, just to give a better idea of what you're looking for? The first one that comes to my mind is Avengers, but I can't imagine anyone spending that much money on an origin film, so I'm interested to know what you had in mind.
I can't speak for Krystal, but, first of all, this shouldn't be an origin film. The Fantastic Four's origin isn't what defined them or made them special.
In the early 1960's, Fantastic Four became a sensation because they redefined what a comic-book should be.
They had visuals and events that were larger and grander than anything we had ever seen, but they did it in a way that made the characters feel more real than characters had before. They were 'grounded' in that way, but that's only one part of the equation. And 'grounded' by itself is nothing. It has to have grounded characters with spectacular settings.
It wasn't a 'coming of age' story. It reinvented comic books and science fiction. I firmly believe that Star Trek and Star Wars would not have been what they were if things like Fantastic Four hadn't come before.
This
shouldn't look like any film we've ever seen before just like the comics didn't look like any comics that had come before. If Fox isn't willing to invest even a fraction of what's required to get the writers and director who can do that, they shouldn't do it.
Making a Fantastic Four film that doesn't capture the elements that made the Fantastic Four what they were is throwing the small amount of money they're willing to spend down the toilet.
Kinberg just said this about Apocalypse:
"We want to tell the Apocalypse story and there's massive scale and scope to telling that story. There's going to be set pieces that I suspect are going to be bigger than anything we've ever done in an X-Men movie before and he's a great character."
Fox should be saying things like that about Fantastic Four, but they refuse to take the property as seriously as they need to.
