After watching the entire first and second seasons my wife still didn't (edit: completely) understand what the dark one is, what it wants, or who Rand is, why he's important, or who the forsaken are and what they want.
I think that says a lot about the shows inability to convey even fundamental foundational information about the series.
ETA: Once I explained everything to her it all made sense, but that should have been the shows job, not mine.
Meh. WoT is my favorite overall series but there are probably entire books worth of material that can be dropped. I bet a competent editor could tell the story in 7-10 books without really changing anything.
Do we seriously need to spend 15 chapters watching Perrin formulate a plan to save Faile, again?
Ebou Dar was really cool. I didn't need to spend four books there.
