It is rare for an adaption to succeed when they seek to go beyond the original work unless they have the author with them, otherwise they baffle newcomers and enrage old hands.
Marvel have perhaps avoided this with their Disney Plus shows, but they often mix and match from different runs as they have far more source material to adapt then they can actually adapt, and often a superfluity of creators, and a readership familiar with retcons. They can afford to discard some things and ramp up others, and giving a show runner with a definite vision to be able to add there own stamp. Moon Knight is a case in point they merged several different stories into a single narrative, retconned the main identities and appointed a show runner with a strong vision in a way which has satisfied the fan base and new viewers.
Can’t see this myself with Wheel of Time or the new Tolkien series. If there is a Dresden Series Jim needs to be heavily involved and that cuts time from writing. The trade off better be worth it.
