There will be some who get giddy with pre-conceived ideas who lose their shit, they need to calm down a bit. There are legitimate structural concerns though which translate bad to the screen.
If you take Ser Jorah surviving the charge it killed any real sense of imminent danger. The NK had his super serious threat neutered there and then. The plot armour was to thick, far to thick. When i then saw Brianne swamped by the dead i was not moved one bit. You knew someone was going to help her and she would somehow be unscathed. Now if a headless or wide eyed Jorah on the edge of death came back and fell there and then you have a real battle set up. Otherwise he should not have been in the charge and we could have avoided the whole unsavoury business of bad fan service in that scene.
