I suspect that it some point for Martin it became more about Dany bathing and changing clothes and having sex than about anything else.
At least she's out of Mereen now, maybe now it'll go somewhere.

Oh yeah, and I'm already excited about Hizdar Lotrak (or whatever his name is) in the show, they made him a complex character whom Dany can play off against. So maybe even Mereen will be somewhat interesting.
