Unfortunately, in the coming books/seasons, she´s becoming even more entitled and megalomaniac. I guess, that´s what happens, when you´re a teenager princess/queen who suddenly has access to alot of power and responsibility at the same time, while coming from an old inbred family whose ancestors state of mind ranged from simply batshit crazy to really good. But yeah, TV-series Dany is way more crazy than book-Dany at this stage.
