I've enjoyed the last two episodes, though last night's did seem a bit bland. That said, I understand that some episodes serve as story progression. I worry that this season will have so much packed into it that certain angles will feel rushed. But then Game of Thrones has always had a sort of 'worldly' feel, where several stories unfold all at once.
I'm curious as to whether we'll be seeing more of the white walkers. If all we're treated to is a headless corpse and a presumably off screen battle, I have to admit I'll be disappointed.
