So I beat Skyward Sword yesterday.  Pretty good, though not without its problems.  But first, I absolutely LOVED the art style.  Really fantastic character designs.  I hope they stick with this style for future Zelda games.  On the other hand, I couldn't stand the dungeons - they didn't feel inventive/creative enough to me, which is unfortunate, since Link's inventory this time around is superb (especially the whip, OH I LOVE THE WHIP).  On top of that, they were realllyyyyy frustrating - not in the sense that they were difficult, but they felt tedious to me.  I enjoyed Twilight Princess' dungeons a LOT more. 
However, the boss battles are fucking amazing.  Every single boss battle was a blast, and made good use of the motion plus swordplay.  I haven't been this impressed with Zelda's boss battles since Ocarina of Time.  That, coupled with the orchestrated boss tracks, made for good times. 
On another note, apparently Groose is turning into a youtube fad/meme: http://www.youtube.com/watch?v=J4KcStmDqRg&feature=related
