The TV show annoyed me. I read the books so many times - whenever a new book came out, I started from the beginning again.
To me it felt like whoever had adapted the book to the TV show had tried their hand at speed-reading for the first time. Ever... And failed.
They failed and made it up as they went along and got characters completely wrong.
I think they cannot continue with the TV series because they have messed up so badly in the first three. Now they've tried speed-reading more and realized they should not have killed off Siuan Sanche as she still plays an important part further in the books.
