Crenelatory Critique

I’ve noticed that fantasy movies tend to have crenellations with way too many merlons and embrasures. In fact, I’ve seen merlons placed at the tip of a king’s donjon! Now how are a king's men supposed handle that? This display of diminutive crenels has got to stop! If this continues, I just know we’ll soon see exposed penetralias, and draughty keeps in the open streets! And then where will we be?
