I’m not sure they got it right. As Stephen King himself noted, THE STAND is a book about medieval Christianity, and while King may not have meant that description in an entirely positive way, the novel draws a lot of power from the idea that the Divine is not and will not be commanded by Man. It’s not enough to believe in God; what’s needed here is to fear Him and His implacable, inexorable goodness, and I don’t know if there’s a mainstream director at the moment who can manage that.
But I might be wrong, here.
In fairness, most King adaptations aren’t very good.
And those that were, were almost all before 1990*.
Apt Pupil is the only exception I’m coming up with, and with that one, they hired a different writer to “fix” the protagonist and the ending.

*Horror genre.
The Shawshank Redemption and The Green Mile were in the ’90s, but weren’t horror. (Apt Pupil in its finished form is also arguably more drama than horror, but the novella it was based on was not. The drama element can fairly be credited to Brandon Boyce.)
