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.
Despite the changes to perrin and matt, i really liked the first three episodes with each one seeming to get better than the last. Lan is playing the warder perfect imo and Thom nailed his music scene as well.
Yeah the music in general has been great.
