In the end, I'm just glad to see some of this hit the screen. Now if they can just find a way to fix the second half of the last book (especially the demise of the Crimson King), I'll be happy.
Elba is indeed amazing, but I just feel like this changes the story too much. I don't know how the racial elements surrounding Susannah and her backstory work with a black Roland. That's a major piece.
