This poll is too black and white. Far too much so.
Skyward Sword was a very interesting game. Focus on exploration and a sprawling overworld was removed to make a more story-focussed adventure with, as OR says, stronger dungeons - in a way, the anti-BotW (EDIT: beaten to that punch twice over!). It did that job quite well, but in doing so it removed some things that some Zelda fans (including myself) like a lot. I love cantering over a full cohesive overworld, and Skyloft just didn’t feel the same, separate as it was from most of the actual gameplay.
The motion controls were excellent. I will defend this to the death. I’m not even only talking about the most tactile and satisfying swordplay the series has had: I’m talking bowling bombs, the aiming, the Beetle... I’m mostly talking bowling bombs.
I also enjoyed the dowsing mechanic, and the silent realms. I enjoy quite a few things the game did anew in fact. I really liked the art style, which I think is better than BotW’s and second only to Wind Waker in the series. And while I didn’t enjoy many of the characters in all honesty, Groose alone made up for most of them.
Skyward Sword does have one big flaw for me, and that’s the sense of repetition setting in early. It repeats the fire and sand/time themes from dungeons two and three in dungeons five and six, in doing so introducing a grand total of no new enemies. (Also it only had two good dungeon bosses, and one was Ghirahim.) It mean that the strong dungeon design was held back by a feeling of ‘seen it all before’. This is taken to its logical extreme with the Imprisoned fights, with the changes in gameplay counteracted by the boss being the same thing each time with the same basic approach.
Skyward Sword was an interesting attempt to shake the series up, after the very iterative Twilight Princess. It succeeded in some areas and failed in others, and ultimately BotW was more successful in that aim. Put a gun to my head and I’d say it’s good, like almost every Zelda game not on the CDi; but it’s a shade of grey that the poll doesn’t allow for.
TL;DR: Dan’s thread is bobbins.
