Cities may not simply surrender. But this one have after the destruction of only some strategic portions. And the army just dropped sword. After that Dany goes berserk (I don't mind as I was expecting it, but as said the trigger was a little odd) and her soldiers start killing unarmed surrendered guys.
Yes Dany is less savage than those rulers, killing the slave owners and opposing families aren't that problematic, but it were cracks in the armor that she wasn't perfect and lovely ruler.
Well, historically the city guard would likely still be executed after the surrender.
But I see what you mean and... indeed. Which makes the screenwriters choice for the precise timing of even more baffling and clearly for shock purposes. It's deliberately forced so no one in the audience is supposed to sympathize with her after that. There's no moral shade of grey. At no moment your convictions are challenged. To people who claimed the White Wakers and the NK weren't interesting because it was manichaeistic... well, there we have it.
Honestly, Attack of the Clones, the second Star Wars prequel, with all of its flaws, actually manages to first showcase Anakin's issues, motivations and inner conflicts better than anything done with Daenerys in the last two or three seasons (which was basically looking depressed and snapping at Tyrion everytime he comes up with his idiotic ideas). Revenge of the Sith, then, it's Shakespeare next to this.Last edited by haxxiy - on 14 May 2019
