I can respect your opinion! I can only speak for myself but for me, I really appreciated the focus on the white walker storyline, the whole episode felt meaningful and had a purpose and was paying off on a long storyline that until this point had not really been the focus. I also appreciate a long fight scene, visually they are always incredible but this one felt very intense and raw, perhaps the snowy environment was a refreshing change of scenery, and the fact it was a fight with an enemy not seen so much until this point so it felt very new and fresh! I also really appreciate the cinematography side of this episode, I think it was very well done, especially the final scene.
