I love them and they have been the most consistent part of the series to this day. Even in a title like Skyward Sword, which I have a lot of problems with, I still find the dungeons excellently designed. I feel as if they are the core of the series and without them the sidequests, overworld exploration and more cinematic moments (all of which are the functional "quiet time" of the series) would not have the impact it does. I also love how dungeons in the game actually feel like some crazy trap filled labyrinth or ancient resting ground instead of an enemy filled hole in a wall. It really enhances the adventurous atmosphere of the game and without them I feel like the series would lose part of it's identity.
