Those stories are too big and too expensive to produce well. Bottom line. Mr. King's books never have translated well to film, with a few notable exceptions, because so much goes on in the minds of the characters. There is external, visible action, of course, but a LOT of the stories in each book are day to day life of normal people... or abnormal people, but doing normal things
Great to read, because we get inside their heads and 'see' the thoughts going on while they go about their mundane lives, but not good for a visual medium. When many filmmakers try to pump up the visual action in the books, it comes off as hokey precisely because a lot of the terror (or sorrow, or humor) comes from what the characters are
thinking.
Revival wasn't one of my favorites (though I wouldn't write it off, as I've only read it once), but I do think it will be much easier to film than The Stand would be, and much less expensive. I cringe at the thought of that ending, though. If it stays as-is, I fear there will be a lot of unintended laughter in theaters. I do NOT think the things at the end will translate as fearsome on the big screen.
