The show ended. Passion naturally dies down at that point. My Dad and I are rewatching the series right now, actually. We're noticing a lot of hints and foreshadowing about Daenerys and her tendency to do violent, impulsive things that we hadn't taken stock of before. The show comes out better when you watch from the beginning while knowing the end.
Dany's character in the books and the show has always walked the line between the Mad King Aerys (her dad) and the noble Prince Rhaegar (her brother), with the whole "flip of the coin" to determine whether a Targ is good or insane being mentioned all the time. She always questions her own actions in the books and has a tremendous fear of turning out like her dad, it is central to her character arc. I refuse to give the show runners credit for that lol
