The sand snakes COULD be great characters as a juxtaposition of a society going all matriarchy in a world full of bad men but outside of the 'most beautiful girl in the world' scene they haven't been impressive or dangerous. That revolt scene should have felt nuts...instead it was ehh, outside of that final kill and it was more about the gore.

Right now all they are is another kingdom mad at King's Landing, of which im like, take a number. Best thing is for em to put it on the shelf and in the final episodes have em roll up to either help the good guys or the badguys
