I can't be the first person to have noted this, but I'll point it out anyway. When the episode opens, we see Roose, kingslaying dagger still in hand, ascending the final steps to the top of one of the Twins, and surveying the slaughter below. While an amazing shot and indeed sequence in itself, I couldn't help but compare it to Blackwater. What struck me was the sheer scale of the carnage outside the Twins; it actually looked like a huge battle/slaughter, as it should. I have always thought that while Blackwater was a fantastic episode, I never really got a sense of the scale that the battle was supposed to possess. All of the shots were too close to the actors, and there was never a large amount of combatants on screen at once. Since the scale of the slaughter outside the Twins was so accurately shown in just one shot, I think Blackwater definitely would have benefited from at least a couple of similar shots. Of course, hindsight is a wonderful thing, but it bears thinking about.
