Dragon fire = exploding buildings??
Definitely not a big problem. Compared to the writing at least... But since when did dragon fire literally explode brick/concrete solid structures??
I got (or thought I knew) why the zombi dragon could be blasting those other walls apart. Because the wall was made of ice, and he’s a zombi Night King dragon with blue fire, right?
But now the dragon is just obliterating everything on screen. It’s just fire, right? Very hot dragon fire, yes. But just fire?
