I understand what you mean now.TSA said:Maybe I am confusing it, so this is what I specifically mean. Look at how Nathan Drake in Uncharted or Ezio in Assassin's Creed moves. Now look back at Link's movement. To me, it's night and day. Everything in Skyward Sword looks a bit goofy, which I guess you can say is the "style" of the game and how it's looked for years now, but to me it looks odd now.
It's not something I would call ugly, but it's more... awkward. The animation itself is fine for the most part, but there is not enough to connect the individual actions of animation. It goes straight from one action into another without connecting them which would create a very game-like feel. Uncharted/AC feel a bit more fluid in this respect, but to me I think hardware is a big reason for this (along with mocap and perhaps Nintendo's naivety). One good thing I've seen a lot more in Skyward Sword compared to the previous games is secondary animation, with a good example of this being the feathers on the bird during flight.
The cutscenes for Skyward Sword however are fine, and Nintendo did a good job in the style they went for. Of course compared to film animation it isn't as good, but they've definitely come a long way from Twilight Princess.
