I thought it was quite a poor episode. Seemed very forced and rushed and the whole fight in the north was pretty unbelievable. Why were there a handy amount of the undead just wandering around waiting to be kidnapped? Why was there a turned bear just roaming on it's own. How on earth did what's his name sprint all the way to the wall, a raven fly all the way to Danaerys then Danaerys manage to get back before that water froze over. I thought that one spear killing the dragon was pretty stupid too. Where on earth did John's rescuer come from and how did John not die after being fully submerged in freezing cold water then spending hours / days?? on a horse not moving. Slightly disappointed.
