If this was written for just readers (especially re-readers) of the series then I would be very disappointed.  Given the audience I thought it was a great adaptation and instead of just looking forward to seeing my favorite parts put into video, now I also get some surprises as well.  The major complaints I have have been stated here.  

I was disappointed with the channeling - not the results of it (that was cool!) - but the presentation of the One Power.  I know it's a lot to ask for the weaving component of the multiple elements but even just adding colors would help differentiate Nynaeve's healing from the others.  How was earth and air the same color?

I just gotta say the trollocs were superbly done.  They were diverse, terrifying (both sight and sound) and demonstrated a unique new menace to the fantasy world.
