Depends on your definition of better, because life sucks for everyone in this story lol. But I'd say yes. She comes into her own, learns to stand up to her brother, and more or less becomes a leader figure. And her relationship with Drogo becomes something strangely sweet, in the book at least. The show hasn't had much time to focus on her story compared to the others so I'm not sure that will ever come across.

Dany's one of my favorite characters though so maybe I'm biased. But I think she's a bad ass in her own way :)
