A bit of spoiler-free stuff from me. And folks... I have Strong Opinions about this series since I played in the setting for a long time. Please tell me if I'm ranting too much or detracting from anyone's ability to enjoy the show.
Anyway, in terms of 'what happened in the books'... the fandom was there first. The novels were there first. I believe showrunners who have stories to tell should do so - but under their own label, so that they stand or fall on their own merit.
The strong feeling I get from watching this show is that the people in charge didn't like the Wheel of Time. They wanted to borrow the upsides of an existing fan base and then go off to do their own thing - which is disingenuous at best. It's one thing to adopt a body of work to fit a different medium and another to essentially do one's own thing completely.
It's even written itself into a corner because of its own affiliations. In the interview the showrunner gave he said that because they already signed the actors for Moiraine and Lan (the former of whom happens to have a producer credit) they have to use them even though their role diminishes a lot after the first book. But this was never a tale about Moiraine, dammit. She's not its protagonist, they are supporting characters. The folks from Edmond's Field are the protagonists.
This is not an adaptation. It's expensive fan fiction, and not very good at that. I am sorry but this Judkins guy is no Robert Jordan. Worse, if it fails, the message it will send is that the Wheel of Time was unsuited to be a TV series, not that this person tried to do his own thing with it.
