All this comes down to three factors....graphics, Graphic, GRAPHICS. I do not personally agree with this assessment. It is rather shallow to judge the majority of the game by the graphics, but with how most people are these days with regard to this subject it is not alarming.
More likely, however, it is just this same Zelda effect I have seen each time one of the games launches. Everyone nitpicks the hell out of it, often in contradictory ways. Everyone always grumbles over Zelda. everybody thinks they know what is best. I have no doubt that Skyward Sword will be an amazing game and certainly an wonderful Zelda game. Remember, people were ready to kill when Wind Waker's graphics were shown and that game was actually all the better having cel sahding (more expressive and flowed better).
To end ask yourself a honest question. Did you put up anywhere near as much fuss when Okami used a similar art style (with regard to its expressiveness)? No. Didn't think so. It is just because it is Zelda. I for one encourage them to use a different style. At least it will not suffer from "sequalitis" like certain other games that only improve the graphics by adding more polygons.
P.S. That being said I wanted to second that Majora's Mask is the best Zelda ever!
Remember, magic is just stuff science has not made boring yet.
