Why are people complaining about the Hound's vision not being shown? This is so ridiculous.
First of all, they have already shown the dead marching with giants among them, so I assume the Hound saw the same picture as Bran did, why waste the time to show more of the same?
And secondly, and most importantly, the main point in that scene was showing the Hound's face and his emotions while he was seeing this vision. For a character that has always been purely pragmatic, a realist, a cynic, to see something as fantastic as the dead army is huge. And I think the actor nailed it perfectly.
Overall, I really liked the episode and how the scenes flow one into each other in usual GoT style, and I also think the plot pace is great.
