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
