I don't understand the white walker anger/confusion. They looked just like the one from the first episode. That was night time and he was wearing a black cloak. Underneath the cloak it was the same type of creature. There were only two white walkers, the one that looked at Sam and as they zoom out there is another on horseback in sweet battle armor that raises his sword and screams. All the rest were wights. Zombies aka NOT the terrifying creatures everyone talks about... Just zombies. I will say, however, that I always thought they would be more elegant and super skinny/tall with more of a ghost feel to them, but they've decided to go with more of a monster vibe and I'm okay with that. The eyes were freaking perfect though.
