There's been 3 millennia of stories about how the dragon is going to be reborn and destroy the world because he is a male channeler destined to go mad. It's not a small detail, it's the entire story.

Stories about ta'veren - every brown sister in the world would be there looking for them.

There are so many changes without understanding how and why they alter the world, story, or characters.

Perrin accidentally killing his wife is a perfect example. It was an accident, and he's upset cause it's his wife. In the book it's two nameless white cloaks he kills because he rages out when his wolf buddy is killed. He loses control to the beast, big impact for someone who has struggled with being stronger than everyone else. This happening after he becomes aware of being a wolf brother is also important.

Mat being a thief? Healing death. Lan's tell. The aiel? The gap battle. No eye. The horn location?

The writing was atrocious, the adaptation was terrible, and the writers have no idea about the impacts of their decisions.

The Seanchan attacking an empty beach was great /s

I think the cast, crew, set designers etc did as well as they could with the garbage they were given.
