Well, I think the main reason people complained about Wind Waker was because of its drastically changed graphical style, but once they played it, they started to like it. I embarrassingly remember that was the way it was for me. I think the main reason people complained about Sunshine was, as the game magazines put it, a lack of innovation. To them, it just didn't push much farther than Mario 64 (except in terms of graphics, which I think are excellent).
