It was interesting how little build up there was to this scene. I was not expecting an epic battle to suddenly take place. Even when you hear the army rumbling, I was taken aback by just how long and involved this battle ended up being. I expected them to just try and retreat once the dragon appeared, yet it kept going and going
It was really interesting, especially for a battle that really doesn't appear at first glance to have a whole lot of plot significance (assuming Jaime/Bronn both survive, all this battle really means is that Dany now knows about the ballistas). I'm hoping them sinking budget into this fight means they're confident they have *another* equally or more impressive battle down the road.
