Too bad the author died before finishing the book. It was a good series - not as great as George RR Martin's A Song of Ice and Fire in my opinion but it has it's own interesting characters and world building.
I haven't seen the TV adaptation. I hope it stays true to the books.
It's good to know the opinion of someone who read it. I know he died before finishing it, but I saw that he left instructions on how to finish it and Sanderson took care of this.
The series has the essence of the books, but takes its liberties. However, I like it and because of it I am reading these books.
