As a reader of the book series (multiple times through), I find the show to be completely trash. First season was ok... In a sense that they didn't fully destroy the fantastic tale spun by Robert Jordan.
Second season is a steaming slop of pig dung. If you have ever read the books or if you enjoy wondrously orchestrated stories with phenomenal characters that have you seeing through the world in their eyes, DO NOT BOTHER WASTING YOUR TIME WATCHING THIS SHOW.
If you know nothing of the books and want to watch a story about an interesting fantasy adventure with weak characters, go ahead and watch it.
The money used to produce the show could have been used to make a much more accurate adaptation that may have rivaled Game of Thrones. But no. That did not happen.
