Of all the complaints in this episode, the dragon being too strong shouldn't even register.
Nah, it's very valid.
If you read anything about Balerion the Black Dread, he was like twice the size of Drogon and breathed flames so hot they were black, and even he couldn't blow apart Harrenhal like Drogon did to the Red Keep. It was very stupid, and very off putting.
Lmao does GRRM literally write things like "the flame was so hot it was black"?
Good Lord.
Fire & Blood
As the last light of the sun faded, Black Harrens men stared into the gathering darkness, clutching their spears and crossbows. When no dragon appeared, some may have thought that Aegons threats had been hollow. But Aegon Targaryen took Balerion up high, through the clouds, up and up until the dragon was no bigger than a fly upon the moon. Only then did he descend, well inside the castle walls. On wings as black as pitch Balerion plunged through the night, and when the great towers of Harrenhal appeared beneath him, the dragon roared his fury and bathed them in black fire, shot through with swirls of red. Stone does not burn, Harren had boasted, but his castle was not made of stone alone. Wood and wool, hemp and straw, bread and salted beef and grain, all took fire. Nor were Harrens ironmen made of stone. Smoking, screaming, shrouded in flames, they ran across the yards and tumbled from the wallwalks to die upon the ground below. And even stone will crack and melt if a fire is hot enough. The riverlords outside the castle walls said later that the towers of Harrenhal glowed red against the night, like five great candles...and like candles, they began to twist and melt as runnels of molten stone ran down their sides. Harren and his last sons died in the fires that engulfed his monstrous fortress that night. House Hoare died with him, and so too did the Iron Islands hold on the riverlands. The next day, outside the smoking ruins of Harrenhal, King Aegon accepted an oath of fealty from Edmyn Tully, Lord of Riverrun, and named him Lord Paramount of the Trident. The other riverlords did homage as well, to Aegon as king and to Edmyn Tully as their liege lord. When the ashes had cooled enough to allow men to enter the castle safely, the swords of the fallen, many shattered or melted or twisted into ribbons of steel by dragonfire, were gathered up and sent back to the Aegonfort in wagons.
