Depending on how its handled, Wheel of Time is an easy bet imo.
1. Diversity cast. I'm not entirely opposed to this in general, but for Wheel of Time it does make sense in that Jordan's vision of the world totally allows for anyone and everyone to be a minority bar a few choice kingdoms. And beyond that like 1/10th of the book characters are actually white, so its not gonna cause a shitstorm like other franchises(see:Ghostbusters)
2. Shock Potential. Its safer than Game of Thrones in some ways, but in other ways its gonna totally hook the audience. Entire kingdoms are matriarchal. The male population has a culling issue tied to the magic system. The female villains are far more competent. All this could go horribly wrong and has potential to be construed into that incel hellscape people were prophesizing Joker would be, but again it all boils down to how its handled.
3. An entirely new and unique world. People correlate fantasy to the Middle ages, castles and dragons, medieval times and low tech. Which is mostly true, at least when it comes to castles and fantasy creatures. Wheel of Time is more Renaissance in its world building amd aesthetics, borderline Enlightenment Era. Some castles are practically skyscrapers. And that's not even factoring in the flashbacks or stasis boxes that bring back some old tech which are far more advanced. I think someone even had lightbulbs at one point. Anyway, 1600s High Fantasy is as close as a description you can make for Wheel of Time, its gonna be visually far more distinct than Game of Thrones or even Lord of the Rings.
There is a lot more that might get people excited about the show or cause momentum for another Game of Thrones pop culture phenom, but these are the 3 main points I have always seen as the main reason why it will rise to the occasion and cause enough waves to be recognized.
