So far the casting is great and it seems like all the actors have a solid grasp of the source material. Lan and Moiraine stand out in particular.
I'm only on the second episode so I can't say much more but from the dialogue and portrayal of the Two Rivers village to the climactic battle scene in the first episode I'm pretty sold so far.
I think that's fairly easy to tone down. I don't think there's anything that's actively unfixable in Jordan's work with a deft change of dialogue and a couple of scene cuts.
