GoT's great, fuck you on about. Dany's plot is just the weakest and most boring shit in it.
Dany's plot gets more interesting when she's thought of as both a villain and a hero. She's the eminent example of why dragons are such a big deal. From the start of the story, she's nobody. Her whole existence is essentially to end up a sex slave (if a high-class one) until the dragons come into play.
Then everything goes out the window and nobody really knows how to react. And as her understanding of just how much power she has grows alongside her frustrations with the state of the world, people start dying. Is it right to impose your morals on others if those morals are things like "rape and slavery are bad"? Guess what, doesn't matter. Dragons. Die.
It's no wonder the mad king ended up the way he did, and he didn't even have dragons. Dany has three, the same number that conquered half the civilized world because the other half wasn't worth bothering with.
Thing is, when Dany makes moral compromises it isn't the kind that people normally make, because instead of having limited power she has unlimited power. Compare her and Tyrion's solutions to Slaver's Bay. Tyrion gives them a chance to adjust in exchange for peace and loyalty, compromising the rights of the slaves for another decade. Dany gives them mass death via dragon, compromising not committing genocide in exchange for immediate compliance regardless of other factors.
