I agree with your criticisms.

I think the opening scene is supposed to be Wisdom training. But whatever it is, it makes no sense. You're right, Nynaeve would never do that.

The White Tower looks nothing like what I pictured from the books.

The line, "the Power inside you" is hideous. It is absolutely not inside anyone, but the ability to tap into it is. Plus as you said, there are no different names for it. It's the One Power. Period.

Tam, the simple farmer who never speaks of his military accomplishments, would not suddenly start spouting Pattern/Wheel philosophy.

"The only thing that matters is what you do," is the exact opposite of the theme of the books for all the reasons you stated.

At first I thought the Myddraal looked cool. Then, not so much. Agree about the Pennywise teeth.

"Whatever happens now, there's no turning back." So true. The show is already in the can. It will suck or it won't.
