Fortunately with Wheel of Time the story has already been told. You can go read it whenever you want. And although I'm not normally a "the book was better" type, for this reader, the show really is disappointing.
Anyway, WoT in particular aside, the basic principle is the same: if you're going to take on producing an epic work, I'd really prefer that you commit to actually finishing it. That's true pretty much regardless of what franchise/property we're talking about.
Not to mention the changed plot beats that I won’t spoil that rob Rand of his big moments and give them to all the female characters, when they already all have major plot moments in EoTW!
So sure it's sad to hear it's not authentic to the books, but I wouldn't have known without reading this discussion and honestly learning that now doesn't affect my viewing experience at all.
