Admittedly I'm not very aware of fantasy anymore these days, but as far as I can tell, the trend has shifted away from ultra-long series, as well as becoming more young-adult oriented, especially female young adults. Wheel of Time, whether it's the original parts or Sanderson's additions, has not aged all that well for Gen Z readers.

I also wouldn't really recommend it to anyone anymore - the series is pretty good as fantasy goes, but in the time it takes to read it, you could read at least four series, or a ton of stand-alone novels, that are as good or better.

I didn't hate Sanderson's writing that much anyway - while I wasn't exactly blown away by the conclusion of the series, most of the ideas were RJ's I believe, so that's not really his fault. Obviously RJ himself would've done a better job with these books, but I'm not sure there's many people out there who'd do so much better than Sanderson.
