yeah,the dungeons were too easy and shorts,but maybe they do this because you are on a portable console and you can't save in the dungeons
anyway,yes,they are kinda weak if compared to other zelda dungeons
I wouldn't call them weak by any means. Let me preface this by stressing the fact that this is my opinion as I know a few posters can be sensitive about such things, but the last 3D Zelda I've played is Twilight Princess, often praised for its dungeon design which I totally agree with, especially when it comes to the usage of new and creative items but I must say that in terms of just pure enjoyment, I am pretty sure that I've had more fun on average in ALBW's dungeons than Twilight Princess.
I think the feeling that the dungeons are too short comes from a few things. Mainly, the fact that you do not need to find the item that will let you progress through the few sections in rooms you have visited before, removing quite a bit of backtracking as a result. Some people obviously still do not agree with this choice, as they feel it removes a certain sense of progression which I can understand, but in my case, I think it was an unnecessary and tedious progress so I'm glad they went ahead with this idea.
Another point that might seem very minor at first but that helps a lot is the constant presence of the map on the second screen. No need to press a button to display it, then switch back to the game, the information on every level of the dungeon is always available to you and in a game that relies a lot on spacial puzzles (moving platforms, wall merging, etc.) it helps a lot. I like to think of it as passing an exam with your notes always available to you as opposed to having to fetch them from your bag each time you need to consult some piece of information.
Finally, Link is just fast in this game, especially since you are exploring what is basically a 2d world. You could probably visit all the rooms in a dungeon in the time it would take you to just find your way hanging from the walls with the iron boots in the Goron Mines. All of your actions are performed at a blazing speed very rarely seen in a Zelda game before and I think a lot of people are still not used to this.
Of course, I do agree that the dungeons are generally shorter than the 3D games but I do feel as though this point in particular is kind of overblown because of the reasons in my post. I also do not feel that the game in general is weaker as a consequence, on the contrary, I think it has succeeded in removing mostly all of the tedious parts of previous Zelda games and all is left now for Zelda Wii U is to expand on this foundation and aim for a bigger game, with grander ambitions while sticking to this formula.
