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.
It means I've faked a terminal illness with all 3 of my ex-wives to keep them around longer, just imagine when they'd have left if I hadn't done that!
