There's plenty of good, fresh fantasy out there. There always was. (So was a lot of bad fantasy.) But the suits in media have refused for decades to allow anything that doesn't match their Joseph Campbellian cultural mythos. Movies have been shoved into the Quest model since Campbell began publishing his monomyth ideas. It is an appealing mythos to begin with or it wouldn't exist, and Western Culture has been conditioned to expect it for generations now. In novels, it can be altered, adapted, or completely ignored, but in film generally, all the differences that add up are ruthlessly removed to force every story into a length of time for people to sit in a theater, and we're back to the same old thing.
The first HP book has the monomyth all over it. Once it was in print and began selling, JKR's amazing skill at media manipulation got the suits interested in fantasy because suddenly they had it shoved in their faces that Fantasy Can Make Money. They had managed to ignore Discworld's success because it grew slowly. A fan of Diana Wynne Jones's work managed to get her wonderfully creative books back in print using the idea that "these are fantasy and will sell just like Harry Potter sold." But DWJ didn't have the clout to keep her stories from being twisted out of recognition, so Howl's Moving Castle took a 90-degree turn and became yet another Miyazaki vehicle instead of the complex psychological portrait it is. Good Omens languished for decades until Neil Gaiman managed to keep enough control over it to keep it fairly true to its origin.
Unless Narrativia can make it happen by keeping control and still getting the funding, I don't want to see more Discworld movies.
[I just reread the first book of Patricia McKillip's Riddle of Stars trilogy, The Riddle-Master of Hed (1976), which is wonderfully creative. Yes, there's a sword, and a birthmark on the hero's forehead, and there are wizards, but it is so very much not just the quest. He is not a quester - he's a questioner, and that's an enormous difference. A movie would lose that totally.]
