At least, so says Mr. Duck in comments to a random post. Actually, now that I saw a bit more, I would like to tweak my previous comments on Hidamari Sketch a bit. It's not quite as limp as it was in the beginning, but the low grade animation remains horrible.
Exhibit 1: It's not even SD.
The annoyance is not the wide face as such, but how much time characters spend in the low-grade mode. I think I haven't seen anything like it since Dragon Half.
Exhibit 2: The high art.
The series has spots which show aspirations for artistry, a-la Windy Tales, but the flashes of it are rather short and far between. They fail to set the tone.
