Thinking about it this morning I think I enjoyed the darkness and lack of clarity at the start, think something GoT does well is that frantic, claustrophobic feeling in the midst of battle. Think criticism of it is totally fair, but for me personally it added to it.
Contrasted nicely with scenes later on where everything’s on fire, e.g. when John’s running through Winterfell and you just see bodies falling from everywhere. Thought that was great visually, really hellish.
