I like most of the changes on the show so far. They've put a lot of stuff right in these two episodes. I like Tyrion and Varys, I love that Arya actually gets to meet Jaqen H'ghar again (great choice to bring back Tom Wlaschiha to play him too; I loved his portayal), and I like the story they seem to have laid out for Bronn by having him team up with Jaime. If we're lucky they will ignore Tyrion's awful story altogether and just bring him to Dany right away.
One thing that grates me though is the tendency to have the more masculine female characters behave in a misogynistic way. Like Arya feeling the need to state that other girls are stupid, or Brienne insulting Podric by likening him to 'a bloody woman'. As if being a strong woman means that you have to distance yourself from women in general. This is something that actively goes against how those characters behave in the books (case in point: Asha uses 'cunt' as an insult on the show while she actively opposes the derogatory way in which men use it in ASoIaF), where they all idolise women and are ranting about the way they are being treated throughout Westeros. This is a pretty big change, and it's consistent too, meaning that Benioff and Weiss purposefully rewrote this aspect to match their own shitty HBO version of female autonomy.
