Where's my GIF of Catelyn Stark bashing Jaime Lannister over the head with a rock? Because that's how I feel.
If the backstory were the main story, I'd ditch this show and never look back.
As it is, while my enjoyment of the main story remains the same and my only complaint with the main story is that, aside from San Niang, the cast is all men (men I like except for the antagonists, but that's a separate matter) there's no way this can ever go on my list of favorites now.
( spoilers are obviously not happy campers )
