Something that occured to me when they first announced the adaptation is that Wheel of Time was revolutionary at the time it was written, but that's because it was coming on the heels of stuff like Dragonlance, Piers Anthony, or some of the more godawful Forgotten Realms paperback novels.
Market-oriented contemporary fantasy was just not in a good place throughout the 80s. It was in a very campy place and I think it's the sort of thing it needed to go through in order to get to a Cosmere type situation.
There were many times while reading the Wheel of Time that I had to just shake my head and sigh and that was before everything went off the rails with endless braid tugging and invented side-plots coming out of left field.
This is all to say that while it is unquestionably epic I'm not sure it's really all that good.
