I actually haven't watched the latest episode, I'm thinking to stack it up so the momentum towards the finale will not break. I don't mind spoilers though.
The issue I think now is Daenerys' apparent "white savior archetype" which I actually disagree. Cp from my tumblr:
1. She never experienced Westeros so she actually doesn’t impose morality or culture to Essos. As long as she can remember she has not been to that place since she left since she was a baby. So she might have a white skin, but she certainly don’t carry the white culture.
2. The series make sure Westeros is not more civilized than Essos. Yeah, Westeros might have banned slavery, but how they see themselves superior and treat wildings like animals say much about themselves. Both regions rape, pillage, burn, whore and do stuff. Since we get to see Westeros most of them time, we see how noble families tend to be dysfunctional and even do stuff such as incest.
3. Her goal is not actually to free every slave, her ultimate goal is to get the Iron Throne and freeing slaves is actually gathering followers that will help her with her ambition. I do not doubt that she sincerely wants to address those sufferings and do what she thinks is right as she herself stopped the rape of village women by Drogo’s soldiers. But she doesn’t dictate any morality of her race, she just thinks slavery is wrong and she wants to free people.
