Ah. I get that they aren't following the books explicitly but they are keeping the characters and over arching story going in the right direction. I'm enjoying it...
... so far. I was enjoying GoT too up until about half way through series 4 when it became clear that they had completely diverged from the books.
They are changing a lot of "rules" and storylines but we'll see where it goes. I can see why they had to change some of it for it to work in a TV format, other things seem weird to change. But I'll hold on to the hope.
Part of me is excited to see a series finale where The Dark One is unmasked like a Scooby Doo villain though
