I've heard they did a decent job with the adaptation.
Not great, but overall solid. (Heard this both from fans of the books and people who never read it.)
Hardcore fans who want every bit of lore detail won't like it though, because no adaptation should ever slavishly follow the original material and they were smart enough to avoid that.
I actually strongly disagree with that. That has been the conventional wisdom for a long time, but I have no idea why as such adaptations usually fail. Adaptations that stick closest to the material tend to be the most successful IMO, particularly in a fantasy setting. Lord of the Rings, Harry Potter, the first four seasons of Game of Thrones, all wildly successful. Minor deviations
outside of characters and main plot in order to accommodate a TV or film medium are fine. But when you start messing with characters and the main storyline, not only does that turn off book fans, but the script writers have a hard time matching book writers in terms of quality in these areas.
As for Wheel of Time, I personally think they butchered it. Felt completely uncompelling. It's the first time ever I haven't watched an adaptation of a franchise I loved through to its completion. I'm literally 10 minutes into the season finale and can't work up enough interest to continue. That's bad. Finales are supposed to be a crescendo! But the bad taste was left way before that. Several of the characters don't exhibit the same traits from the books, and they radically altered the story. If you're going to do that, the result sure as hell better be an improvement, but it wasn't. The biggest deviation feels entirely too much like it was made solely to suit their focus on the Aes Sedai rather than on the Dragon.
I actually don't know anyone who
loved the Wheel of Time TV series. The best I've heard is a hesitant "it was...good", and I've heard a lot worse than that.
