At this point, Daenerys Targaryen is most definitely not Cersei Lannister.
But just because she isn’t the worst choice for the Iron Throne doesn’t make her a good one, and “The Spoils Of War,” in fact, suggests she is actually a pretty terrifying one.
To say the least, this was an absolutely massive turning point for the character, and given the expectations about where things are headed, it looks like things are going to be getting a lot worse instead of getting better.
We’ve seen her do some horrific things over the years (the burning of Randyll and Dickon Tarly springs to mind), but nothing compares to Destruction of the Great Sept of Baelor, or the general terror Cersei has wrought as a royal puppet master.
