I'll agree that the House of the Undying was handled much better in the book. I've been okay with most of the changes the show has made, though this is an instance where they really fumbled things. The fact that this scene was literally the only interesting thing to happen to Dany this season doesn't help matters any.

My only problem was that the Dany arc could have been wrapped up in like 3 episodes, and they drew it out way too long even though I liked the conclusion.
Bad as it was in the show, this issue was much worse in the book. Her chapters dragged on and on, with little to nothing of interest actually happening. They could have removed all but her very last chapter in the book (which won't be adapted until next season) and we really wouldn't have missed much of anything.
